The 5 criteria Ableton uses to determine sample slicing positions — 8 sources to discover free Max for Live devices beyond them

When you drop a sample into Live and chop it up, the positions of the slices are determined not by your own ears, but by the criteria provided by Ableton. Slicing by transients, by beats, by warp markers, by equal divisions, or by placing them yourself. It is limited to these five.

In most cases, this is enough. Or rather, it is sufficient because these five are well-designed. However, when you keep chopping the same two-bar loop over and over, there comes a moment when you want a slicing method that is different from all five. You want to slice at a point that doesn't land on a beat or a transient. You want the slicing position itself to change every time. You want to capture and slice the sound currently playing on the spot, rather than preparing the material as a file.

Beyond that, there are Max for Live devices. This time, I have selected eight of them, all free, and arranged them based on the single point of what they use to determine the 'slicing position'.

There are two things I should state honestly upfront.

First. I have not run these eight devices in Live. What I am writing is based solely on what can be read from the author's descriptions and official Ableton documentation. The scope of this article goes as far as 'this device is described as slicing in this way,' and does not include 'this is how it sounds when actually played.' I am introducing tools intended to be used without actually using them. Please read with that in mind.

Second. 'Chopping' itself is something anyone who owns Live can do. Both Auto Pan and Beat Repeat are included in Intro, and Ableton themselves describe these two in their official edition comparison table as 'beat-synchronized chopping effects' and 'controlled or randomized repetitions of an incoming signal.' This article is not about 'not being able to chop with stock tools.' The criteria the stock tools use to determine slicing positions are limited to five—this is about what happens when you go beyond that.

About the labels in this article

The sources introduced are labeled to indicate the language barrier.

🟢 Japanese — Japanese content. Can be read as is
🟢 Understandable via video — English, but includes a demo video by the author, so you can see what is happening by watching the operation
🟢 Understandable via operation — English, but there are only about three knobs, so you will understand by touching them
🟡 Simple English — English, but you only need to read short explanatory text
🔴 English proficiency required — Requires English reading skills

For those who are not comfortable with English, the structure is designed so that even if you only follow the 🟢 ones, you can progress from the stock foundation to three devices you can actually touch.

First, what you need to know: Who can use them

All the devices introduced hereafter are free, but the foundation required to run them may cost money. It wouldn't be fair to omit this, so I will write it first (all as of August 7, 2026, based on the official Ableton website).

• Live Suite — Max for Live is included from the start. No additional cost

• Live Standard — Can be used if you purchase the Max for Live license separately (¥21,800. Crossgrade is ¥10,800 if you own Live Standard and the standalone version of Max/MSP)

• Live Intro / Live Lite — Cannot be used. Not eligible even if you buy add-ons

The official Ableton help phrasing is as follows.

There is one more thing relevant to those using Intro. The 'Slicing' feature in the official edition comparison table—described as 'Slice audio to a Drum Rack or Sampler instance.'—is marked with '×' for Intro, and '•' for Standard and Suite. In other words, the stock slicing feature that serves as the foundation for this article is not included in Intro. On the other hand, Simpler, Drum Rack, and the aforementioned Auto Pan and Beat Repeat are available in all editions.

If you just want to try it out, there is a way that doesn't cost money. As stated on the Ableton Japanese page, 'You can try all the features of Live 12 Suite for free for 30 days,' the free trial is equivalent to Suite. Max for Live is also included there. The official help phrasing is 'You can use Max for Live during the trial period as well since it is included with Suite.' However, there are three conditions: 'A trial can only be used once.', 'It is not possible to authorize the trial offline.', and you cannot buy Packs from the webshop during the trial. Since all the devices introduced this time are distributed outside of Ableton, the last condition is irrelevant.

Furthermore, as of August 7, 2026, the official Ableton store is running a 'Domestic-only sale until Wednesday, 8/12' with '25% off Live!,' making Suite ¥84,800 → ¥63,600, Standard ¥52,800 → ¥39,600, and Intro ¥11,800 → ¥8,850. The Max for Live add-on (¥21,800) is not eligible for this sale, and upgrading from Standard to Suite is also not eligible (the offer applies to the purchase of Live 12 itself and upgrades from Live Lite). Since there will be only a few days left by the time this article is published, please check the deadline.

First, what you need to know: The 5 criteria the native software uses to determine slice positions

There are two ways to start slicing samples in Live. You can either right-click an audio clip and select 'Slice to New MIDI Track' or load a sample into Simpler and set it to Slicing mode. The way slice positions are determined differs slightly between these two methods.

For 'Slice to New MIDI Track', the official manual states the following.

Beat resolution / clip transients / Warp Markers. These are the three systems. And there is an upper limit.

Since a Rack has a maximum of 128 chains, you are not allowed to execute a selection that results in more than 128 slices in the first place.

For Simpler's Slicing mode, there are four options for 'Slice By'.

Transient (automatic placement at the attack), Beat (beat division positions), Region (equal division), and Manual (placing them yourself by double-clicking). And there is also an upper limit for automatic transient placement.

No matter how much you increase the Sensitivity, it is capped at 64 slices. Incidentally, this number 64 perfectly matches the fact that MySlicer, which appears later, states 'you can choose from 1 to 64', and the author of SliceTool warns that 'Simpler can only hold 64 slices, so if you use them all up on a long sample, the rest will be empty.' The native upper limit is a wall that third-party developers run into every day.

In summary, the criteria the native software uses to determine slice positions are transients / beat resolution / Warp Markers / equal division / manual. The upper limits are 128 (Slice to MIDI) and 64 (Simpler's automatic transient placement).

The destination for the slices is also actually quite well-equipped. Since this is rarely introduced in Japanese, I will note that in Live 12.1, 7 types of presets were added to 'Slice to New MIDI Track' as part of the Core Library. Quoting the list from the official help directly, they are: Default, Drums Gritty, Drums Lofi, Drums MPE, Low End Boom, Sampler Zones MPE, and Vocal Slices. Ableton itself describes Drums Lofi as 'perfect for hip-hop, chillout, and lo-fi production' and Vocal Slices as 'for vocal processing,' which is content that hits the mark for the audience reading this account. It also states, 'As of Live 12.1, all Slice to MIDI presets offer Macro Variations and Info Texts for each Macro,' so the macros come with variations and explanatory text. It is more accurate to consider the native scope to include the entire process up to the point where a Drum Rack is assembled the moment you slice.

Furthermore, the same help also states, 'To download legacy Slice to MIDI presets no longer available as of Live 12.1, you can submit a request using our Support Contact Form.' There are old presets that disappeared in 12.1, so if you were used to the previous behavior and were wondering 'where did that go?', it seems you can obtain them by contacting support.

Everything from this point on is about what lies outside these five criteria. I will state one thing first: 'It is not the case that you cannot rearrange them with the native software.' The official manual writes this in the 'Slice to New MIDI Track' section.

Ableton itself provides guidance on how to make things interesting by randomizing after slicing. Live 12's MIDI Tools also include Chop (up to 64 divisions, with random variations possible for start/end times) and Recombine (Shuffle / Mirror / Rotate). What lies outside is not 'rearranging,' but 'how to determine the slice positions.'

Section 1: First, how much can be done natively (2 items)

1. Live 12 Reference Manual (Ableton Official)

🔴 English proficiency required | Official documentation (English)

This is the source of the numbers and options I have cited so far. The Simpler section describes the four choices for 'Slice By' and the limit of 64, while the section on converting audio to MIDI describes the three systems for 'Slice to New MIDI Track' and the limit of 128. You only need to read Chapter 2, and both are just a few pages long.

One note of caution: There is no Japanese online manual for Live 12. Opening `/ja/live-manual/12/` redirects to the English version (the same applies to German, Spanish, and French, so it is not just a Japanese-specific issue). If you want to read it in Japanese, I think the Help menu accessible from the Live app or the Japanese explanatory articles listed below are faster.

Also, since this is a common stumbling block for readers, I will note that as of Live 12.2, the 'Edit' button for Max for Live devices has been removed. If you want to open the inside, right-click the device title bar and select 'Edit in Max'. If you follow old tutorials, you will get stuck here because you won't find the button.

Recommended for: Those who want to verify what is happening in their own Live instance using the original source rather than someone else's explanation.

2. Slice to New MIDI Note (SLEEP FREAKS)

🟢 Japanese | Tutorial site

This is an article that turns the native 'Slice to New MIDI Track' into a step-by-step guide in Japanese. You can follow the process from right-clicking an audio clip to having it arranged in a Drum Rack, complete with screenshots. I recommend going through this once before reading the remaining six articles in this series. This is because if you don't have a physical understanding of 'how it cuts natively,' you won't be able to judge how the subsequent devices differ.

There are other articles in Japanese explaining native slicing, such as 1001sec.[murbo]'s 'Slicing sounds in Ableton Live. Let's slice.' which covers the same process with a different writer's approach, and Muri-nai Kurashi's 'Let's have fun sampling in Ableton Live: Preparing for finger drumming using Slicing mode' (January 12, 2019), which is written from the perspective of Simpler's Slicing mode. There is plenty of solid information in Japanese regarding the native foundation.

Recommended for: Those who own Live but have never used 'Slice to New MIDI Track'.

Section 2: Going outside (2 items)

This is where the real topic begins. First, let's start with the two that are furthest from the 5 native criteria.

3. bve.slices (ithkaa / Benjamin Van Esser)

🟡 Simple English | maxforlive.com (English, no demo video)

Of the 8 items this time, this is the only one that can be definitively said to have 'no native equivalent'.

Native slicing, whether in Simpler or 'Slice to New MIDI Track', is based on the premise of dropping in an existing file. bve.slices is different in that regard. The author's description is as follows:

(The double space in "slices of live" in the quote is as it appears in the original text.)

Record the sound currently playing on the spot, divide it equally, and play it back using a MIDI keyboard. The process of preparing source material disappears. As the word "performers" is included in the author's description, it is a tool that leans more toward performance than programming.

There are three points where you might get stuck during installation.(a) The distribution is a ZIP file, not a standalone .amxd, and it contains two devices: bve.slices and bve.sendtoslices.(b) The Device Type field on maxforlive.com says "Audio Effect," but you place the bve.slices device itself on a MIDI track (you place bve.sendtoslices on the audio track side).(c) The last update was January 19, 2021, and the page description is still from the Live 10 generation.

Recommended for: People who want to build beats by hand rather than programming them. People who find the process of preparing source material itself to be a hassle.

→ https://maxforlive.com/library/device/3251/bve-slices

4. MySlicer (opticon93)

🟡 Simple English | maxforlive.com (English, no demo video)

What makes this device interesting is thatthe author intentionally keeps the "slicing side" minimal. This is clearly stated if you read the author's own explanation.

"Sorry, no beat/transient detection." Slicing is limited to equal divisions of 1 to 64. There is no waveform editing either. It lacks the Transient, Beat, and Manual modes found in the stock Simpler, offering only a Region-equivalent option.

Instead,the side after slicing is exceptionally robust. It has a 16-step sequence, and you can draw four layers for each step: Velocity / Slice / Pitch / Speed. This Speed lane—which allows you to specify the playback speed for each step—is not available in the stock Simpler or MIDI Tools. In addition, there is a dedicated Stutter column for specifying values from 8n to 128n, and a Rest knob that determines the probability of rests being inserted.

In other words, this is a device that goes all-in on "how to rearrange the sliced parts" rather than "where to slice." It might be more accurate to think of it as something you use after chopping with the stock device.

One note of caution: there is no mention of Live 12 anywhere on the page (I checked the comments section as well). An update was made on September 1, 2025, but the author's comment was, "Hi, folks. A long overdue update so that it stays on top."—it was an update to keep it at the top of the list, not an announcement of Live 12 compatibility.

Recommended for: People who want to fine-tune the rearrangement after slicing rather than the slicing itself. People who want to change the speed for each step.

→ https://maxforlive.com/library/device/7571/myslicer

Section 3: Randomly skipping slice positions (3 devices)

The stock Beat Repeat also has Chance (probability of triggering) and Variation (randomly changing the grid size). However, where Beat Repeat captures is determined by Interval and Offset, and that part is not random. These three devices move the capture location itself.

5. Angel Chopper (liminalbleeps)

🟢 Understandable through operation | maxforlive.com (English, 3 knobs)

The author's explanation perfectly captures the nature of this device.

"Like clicking frantically over a waveform." It keeps creating slices at random positions from the incoming audio. Tempo sync can be toggled on or off.

The UI consists of only three knobs: `variance`, `interval`, and `max length`, plus a SYNC button and a resolution dropdown. This is where `max length`—the design only allows you to set an "upper limit" for the length, and no lower limit can be specified. This specification can also be inferred from user comments in the comments section.

The use cases mentioned by the author, such as "long tones and vocal recordings," seem to align with this character of "varying lengths, including extremely short ones." Conversely, it does not seem to be a tool for creating chops that sit perfectly on the beat.

Note that the identity of the "famous electronic musician" mentioned by the author has not been disclosed. Since the comments section is just full of speculation, I will refrain from touching on it here.

Recommended for: People who want to break up pads, long tones, or vocals in a way that doesn't follow the beat. People who like tools that can be operated with just three knobs.

→ https://maxforlive.com/library/device/14550/angel-chopper

6. Rhythmic Crazy Slicer (Remo De Vico)

🟢 Understandable via video | YouTube (English, demo by the author) + 🟢 Japanese explanation available

Out of the eight, this is the only one that already has a Japanese explanation. project of napskint wrote a dedicated article on July 29, 2026. It is a site that consistently reports on free distributions in Japanese, and you can read about the source and installation in Japanese. If you are not comfortable with English, reading that first is the fastest way.

The "method for determining slice positions" for this device is clearly written in the Controls description on the author's site.

You "draw" the start point of each slice yourself with the multislider. Then, when you press RANDOM, the start points are assigned in a non-repeating pattern. Draw by hand or let random numbers decide. This is a determination method not found in any of the five standard criteria. How to use it is: "Insert your sound sample and press play on your Ableton project."—just insert a sample and play Live. A PDF on how to use it is included with the download.

There is a demo video by the author titled "Slice Any Sample into Unexpected Rhythms [Free Ableton Tool]" (link at the end). Even if you can't understand the speech, you should be able to see what happens when you move the multislider.

There are two practical points to note. The distribution is in the "pay what you want" format on Gumroad. It is displayed as "¥0+," and the price input field has a suggested amount faintly entered (if opened from Japan. The author's setting is €15, and it seems to appear converted to yen at the day's rate. As of August 8, 2026, it was displayed as ¥2,731). You can leave it blank or enter 0 to get it for free. Another thing is, there is no mention of Live 12 on either the author's site or maxforlive.com. The "Live Version Used" column on maxforlive.com just says 10.1, and as described later, this is not a field for guaranteed operation.

Recommended for: People who are not good at English and want to see it in action first. People who want to try drawing the slice positions by hand.

→ maxforlive.com page / Author's site (distribution source) / Author's demo video

7. BEAST Repeat (Dillon Bastan)

🟢 Understandable via video | YouTube (English, walkthrough video available)

The author writes this themselves.

An expansion of the stock Beat Repeat. I will be upfront about this, but the differences are clear. The pitch of the stock Beat Repeat can only be lowered, and because it uses a resampling method, the speed changes along with it. The BEAST Repeat feature list states the following:

("spary" is a typo in the original text)

You can shift the pitch up or down while maintaining the speed. You can randomize the direction of reverse playback. You can shift the formants. Furthermore, you can apply Variation—which only affects the Grid in the stock version—to the Interval and Gate as well. The position of this device is that the Interval itself, which determines the cut position, can fluctuate.

The creator, Dillon Bastan, is also the person who made Inspired by Nature, an official Ableton pack included with Live 11 (the distribution site links to the official pack page). However, the handle on maxforlive.com is "ndivuyo," and I have not been able to confirm primary information where the person explicitly states they are the same. The extent of what I have verified is that both the distribution site and the demo video channel are under the name Dillon Bastan.

Two things regarding acquisition. There is no download button on maxforlive.com (the page exists, but distribution is on the creator's site). And on the creator's site, you must enter your email address even for a free download. You do this by entering 0 in the price field and clicking "Download for Free!", and the page also states, "Note: You might have to disable your ad blocker to download!"

This is the only device for which the creator explicitly states the supported version. The distribution page says, "Works with Live 10 and up!" Out of the 8 items this time, this is the only one where this is written.

Recommended for: People who use the stock Beat Repeat but find it lacking. People who want a stutter that can also pitch up.

→ Distribution site (Dillon Bastan) / Walkthrough video / maxforlive.com page

Section 4: Carving and sculpting without cutting (1 item)

8. ULTRACHOP (weightausend)

🟢 Understandable through operation | maxforlive.com (English)

I will admit upfront that this is the only one that is close to the stock version. The creator's description is as follows:

It is a type that carves sound using waveforms (wavetables). Instead of cutting and rearranging samples, it makes the sound appear chopped by carving away the amplitude of the playing sound with a curve. This category uses the same concept as the stock Auto Pan-Tremolo. In Live 12.3 (November 25, 2025), it was renamed and expanded from Auto Pan, adding Tremolo mode, waveform selection from Sine to Random / Wander / S&H, and exponential/linear ramps. And this is included in all editions, including Intro.

Beyond that, there are three things that can be read as unique to ULTRACHOP. Special waveforms that change the harmonics themselves (the creator writes, "special high frequency 'impulsive' wavetables that can drastically affect or enhance the harmonic components of your audio source"). A design where distortion is applied to the modulation waveform side rather than the output ("a distortion that is applied to the stuttering wavetable rather than its main output, creating a more brutal stuttering effect"). And a linked device that allows you to draw waveforms yourself is provided separately. I think it is a tool for people who are more interested in "carving" than "cutting." The creator writes that tooltips appear when you hover over parameters, so you should be able to grasp it while playing without having to read an English manual.

There are two conditions. One is a disclaimer from the creator themselves, stating that it is still in the experimental stage.

Another factor is licensing. The License field for this device is CC BY-NC-ND, meaning no modifications allowed. Among the 8 devices this time, this one has the strictest conditions.

Recommended for: Those who want to "carve" rather than "cut." Those who create texture-oriented sounds.

Bonus: How to read pages on maxforlive.com

While researching these 8 devices, I realized that there are tips for reading pages on this site, so I have summarized them here. If you don't know these, you will waste time getting confused before you even download anything.

"Live Version Used" is not a guarantee of operation. This is just a declaration of the Live version the author used for production; there is no field on the page for compatibility range. Regarding the 8 devices this time, Angel Chopper and BEAST Repeat are 12.0.5, MySlicer is 11, bve.slices is 10.1.30, ULTRACHOP is 10.1.18, and Rhythmic Crazy Slicer is 10.1. It is not set in stone that it won't work just because the number is old, but it also doesn't mean it's compatible with Live 12 just because it's new. In fact, for Slicerizer, which was just added on August 1, 2026 (a new work by the same author as MySlicer), the Live Version Used is listed as 11.

Some devices do not have a "Download Device" button. If the distribution is hosted on the author's own site, the maxforlive.com page exists but contains no file. In this case, BEAST Repeat and Rhythmic Crazy Slicer fall into this category. When you can't find the button, check the links in the description or the author's profile.

The "Downloads" number is not an indicator of popularity. As mentioned above, externally distributed devices will have this number stuck at 0 or 1, so it is meaningless to compare them with directly distributed ones.

The "License" field is worth checking properly. Even among the 8 devices this time, Angel Chopper / BEAST Repeat / Rhythmic Crazy Slicer are "None" (= the author has not selected anything), MySlicer and bve.slices are CC BY-NC-SA, and ULTRACHOP is CC BY-NC-ND. The term "free M4L device" only applies to the acquisition stage; the conditions differ for each one. It is also not accurate to group them all under the term "open source." By the way, even if this field says "Commercial," it does not necessarily mean it is paid; sometimes this label is attached to free devices included in official Ableton packs.

You do not need to register an account to download (at least for directly distributed devices, I confirmed that .amxd files can be downloaded without logging in). Logging in is only required for ratings and comments.

There is a protocol for searching. If you are constructing a URL without using the search bar, such as `https://maxforlive.com/library/index.php?by=any&q=slice`, you need both `q=` and `by=any`. If you only use one, it will silently return a list of the latest devices instead of search results. Since no error is displayed, you might mistakenly think the search was successful.

What is the situation like in Japanese?

I will write honestly about the scope of my research.

There are several Japanese articles introducing free Max for Live devices. Older ones include Mawaru Sebone from 2016, Kadomaru-san from 2017, Hylen Lab from 2022 and 2024, Gloveity's series from 2024, and shunnarita.com from May 2026, covering 10 years of content.

What is interesting is that after checking all of these, I found that not a single sample-slicing device was included. They are generous with synths, modulators, MIDI utilities, and visualizers, but slicers are completely missing. I also followed a thread on X that introduced over 20 Japanese M4L devices, but there were no slicers there either.

On the other hand, there are Japanese articles for individual devices. As I wrote earlier, Rhythmic Crazy Slicer was covered by project of napskint on July 29, 2026, and the same site also has three articles on a real-time glitch/stutter M4L device called Drox. The official Ableton Japanese blog also has articles covering the Max for Live built-in Buffer Shuffler from 2014 and 2019.

So, that is as far as I can go in this article. As far as I could tell from searching through full-text searches on note, site searches on project of napskint, Computer Music Japan, DTMer.info, and SLEEP FREAKS, as well as YouTube Japanese searches, I could not find any Japanese articles that compared free slicer-type devices distributed on maxforlive.com by lining them up along a single axis of "what determines the slicing position." There are some Japanese introductions for individual devices. The value of this article lies not in finding new things, but in the way they are arranged.

Summary: What determines the slicing position

I will rearrange the 8 sources based on "what determines the slicing position."

・Material onset | Native: Simpler's Slice By = Transient (max 64) | The 8 selected here: None (Not a single transient detection type is included)
・Beat/Equal division values | Native: Slice to New MIDI Track / Slice By = Beat/Region | The 8 selected here: MySlicer (equal divisions of 1-64), bve.slices
・Random numbers | Native: Beat Repeat's Chance / Variation (though capture position is fixed) | The 8 selected here: Angel Chopper, Rhythmic Crazy Slicer, BEAST Repeat
・Volume curve | Native: Auto Pan-Tremolo (all editions) | The 8 selected here: ULTRACHOP
・Input during performance | Native: None | The 8 selected here: bve.slices + bve.sendtoslices

When lined up like this, it becomes clear that "slicing by onset" is the strongest in the native version. There was not a single device among the 8 selected here that had transient detection. If you just want to create satisfying chops, Simpler's Transient setting is enough.

The two areas where there is a clear meaning to going outside are random numbers and input during performance. Especially the latter—capturing and slicing the sound that is playing on the spot without preparing the material as a file—has no native equivalent.

For those who are not good at English: You can proceed through 4 sources using only Japanese and video in the following order: Source 2 (mastering native features in Japanese) → Source 6 (Rhythmic Crazy Slicer with Japanese commentary) → Source 7 (BEAST Repeat with walkthrough video) → Source 5 (Angel Chopper with 3 knobs).
For those who can read English: Go through the relevant 2 chapters of the manual in Source 1, then move on to Source 3 (bve.slices). That is the one furthest from the native version.

One last thing. I have not run these 8 devices. What I wrote is limited to "what is written about how they slice," not the result of playing them. Since most of them are free and do not require registration to download, please try installing and checking the ones that interest you. If I find anything out after running them, I will add it to this article.
