Sampling in Ableton Live 12: Chop, Slice and Resample with Simpler

A sampled loop already contains a performance: attacks, spaces, ringing cymbals and small timing differences. Chopping gives you a way to play that performance in another order. In Ableton Live 12, Simpler turns those pieces into a MIDI instrument; resampling turns your new performance back into audio.

You will take the first bar of the Core Library loop Break 90s Vinyl 88 bpm, divide it into eight pieces, write a different rhythm at 92 BPM, and print the result. The complete exercise uses no additional Factory Packs. Keep the untouched loop available so you can compare your decisions. If tracks and clips are new, start with our Ableton for beginners guide.

1. Separate the recording from the instructions

An audio clip contains a reference to recorded sound. A MIDI clip contains instructions: which note starts, when it starts, how long it lasts and its velocity. Simpler connects the two. The note chooses what Simpler plays; its playback settings decide how that sound responds.

The workflow has three editable stages: prepare recorded audio, play selected pieces with MIDI, then record that performance as another audio file. Printing creates a new source for another round of chopping; keep the MIDI version when you want to change the slice choices later.

Our Live 12.3 and 12.4 update guide gives the wider version context; this lesson uses the established Simpler workflow. Save a new Set before experimenting. Locate Break 90s Vinyl 88 bpm in Live’s browser and drag it onto an audio track. This inventory item lives in Core Library/Samples/Loops/Drums/Full; searching the exact name avoids similarly named breaks. Listen once without effects. Count four quarter-note beats, then identify the next downbeat.

A repeating pattern is an ostinato. Your job is to change its organization while retaining enough repetition to recognize it. You do not need to identify every drum inside this mixed loop. A slice can contain several drums together; slicing does not separate instruments.

Changing a slice boundary edits the sound assigned to a key; moving a MIDI note edits when it plays. Keep the boundaries fixed while comparing note patterns.

This exercise uses Ableton’s Core Library. Check Ableton’s content-use terms before releasing or distributing the result. Original compositions require added material and significant transformation; commercial sampling products need express written consent. Those permissions do not automatically cover outside recordings: use your own recording or check the source’s license before substituting another sample. Our hip-hop guide explains sampling permissions in more detail.

For the mode comparisons, create a MIDI track, load Simpler from the browser, and drag the loop into its sample display. Make a short MIDI clip and draw a C3 note to audition Classic and One-Shot. Keep the original audio track stopped. In section 3, replace this full-loop sample with the prepared one-bar audio clip.

2. Choose Classic, One-Shot or Slice

Use Classic when you want a sample to behave like a pitched instrument. It has an ADSR amplitude envelope and optional looping. With Warp off, higher notes play the sample faster as well as higher. C3 plays the original pitch before transposition. With Warp on, pitch changes can stay synchronized to the Set’s tempo.

Choose the playback response before editing the MIDI. Classic is useful for held, pitched sounds; One-Shot is monophonic and suits hits or short phrases; Slice turns positions within one recording into playable addresses. The three modes share warping but offer different envelope and voice controls.

For a held texture, enable Classic’s Loop and hold a note. For a short drum hit, leave looping off. The amplitude envelope shapes one note’s level over time. Attack is the rise after note-on; decay moves from that peak to the sustain level; sustain is the level held while the note remains down; release is the fade after note-off. The sample can still run out before the envelope finishes unless looping supplies more sound. Our Draw an ADSR Envelope exercise separates these times from sustain, which is a level. A long release can make short MIDI notes sound connected.

Live 12.4.15: Classic study shows the available first bar in yellow and the excluded remainder in gray. The numbered areas identify Classic mode and its amplitude-envelope controls, visible together without expanding the device. Warp is enabled in Beats mode. Cropped to Simpler; the Session grid and other window areas are omitted.

One-Shot removes looping and uses one voice. In Trigger, releasing a key does not stop the sample. In Gate, release starts the Fade Out. Test both with a very short note, then a long note. If both sound equally long in Trigger, that is expected. To shorten Trigger playback, change the region or fades.

Live 12.4.15: One-Shot study has Trigger selected; Gate is the alternative below it. Fade In and Fade Out both display 0.10 ms in this comparison state. The first bar's waveform is yellow; the teal tint is the region selection highlight. Cropped to Simpler; other window areas are omitted. A short MIDI note in Trigger does not cut the region off at note-off.

Use Slice for this exercise. Each adjacent MIDI key selects another piece, rather than transposing one whole phrase. Choose Mono playback first: a new slice interrupts the previous one. Poly permits overlap; Thru continues from the chosen slice through the remaining region. Thru can explain a mysterious “slice” that plays the rest of the loop.

Compare Mono and Poly using a ringing slice: Poly allows its tail to overlap the next entrance. Keep Mono for the fixed exercise.

3. Make the first bar follow the tempo

Set the project to 88 BPM initially. Check whether the file begins on the first audible downbeat; its name alone does not establish that. Double-click the audio clip to open Clip View and enable Warp. Listen for the first downbeat, zoom into its attack, right-click its transient marker and choose Set 1.1.1 Here. Locate the next bar’s downbeat by counting four beats. Double-click its transient marker to make a Warp Marker, then drag that marker to 2.1.1. Set the loop Position to 1.1.1 and Length to 1.0.0; enable Loop. The warping chapter explains these markers.

Live 12.4.15: two crops show the source clip’s one-bar loop, Warp enabled and boundary markers. Interior transient marks remain gray. Other window areas are omitted. This establishes marker placement, not audible downbeats.

For this equal-region exercise, use a uniform stretch between the two bar-boundary Warp Markers; remove interior Warp Markers that alter that stretch. Check the eighth-note positions before continuing. If you need uneven warping to repair the source, choose Beat at 1/8 instead and verify the eight slice addresses again.

Procedure schematic, not a Live capture: the two bar boundaries anchor a uniform stretch, with no interior Warp Markers changing its timing. Eight equal source-time regions then coincide with the eighth-note positions. Confirm the source attacks by listening; this diagram does not establish where the recording’s downbeats are.

Change the Set to 92 BPM. Listen with the metronome over several repetitions. A steady offset suggests the start is misplaced; an offset that grows suggests the bar length or tempo interpretation is wrong. A convincing first beat alone is insufficient. Check the final beat and the return to beat 1.

For quarter-note BPM, divide 60,000 by the tempo to get one quarter note in milliseconds. Halve that for an eighth, halve it again for a sixteenth, or multiply the quarter-note duration by four for this 4/4 bar.

At 92 quarter-note beats per minute, the eight equal pieces of a one-bar region each occupy an eighth note, about 326.1 ms. A sixteenth lasts about 163.0 ms. These are target musical durations after warping, not claims about the original recording’s individual drum attacks or exact file length.

Start with Beats warp mode for this drum break. The manual describes it as suited to rhythmic material. Listen for repeated tails, gaps or softened attacks when changing tempo. Compare the same passage at the same level before choosing another algorithm. Re-Pitch couples tempo and pitch; it is a creative choice when you want that linked change.

Drag the prepared audio clip into an empty Simpler on a MIDI track. Live retains the clip’s manual warp settings and uses its selected start/end or loop region. Confirm that exactly one bar is available. Simpler’s Warp as… fits its region into a stated duration; a wrong half/double interpretation still needs correction. Practice the arithmetic with Tempo Math.

Keep the audio track muted while playing Simpler.

4. Slice by what you want to preserve

Transient follows detected attacks. Raise Sensitivity to expose quieter events; lower it if a cymbal tail produces too many fragments. Audition every boundary. Detection finds changes in the waveform, not necessarily the musical unit you wanted. An attack with its surrounding ambience often works better than a tiny isolated peak.

Live 12.4.15: Transient study uses Slice By Transient at 50% Sensitivity with Mono playback. The visible boundaries follow detected attacks in the yellow first-bar region; the gray audio is outside it. This comparison uses Trigger. Cropped to Simpler; other window areas are omitted. The fixed exercise below uses Region instead of relying on this detected boundary count.

Beat follows musical divisions. Choose 1/8 when you want eighth-note chunks of a correctly warped bar. This can preserve the movement between attacks, including ghost notes. It can also cut through a sound. Musical grid alignment does not guarantee a clean acoustic boundary.

Live 12.4.15: Beat study divides the selected first bar into eighth-note slices. Highlight 1 marks Slice By Beat and Division 1/8; highlight 2 marks Warp and the Beats algorithm. Trigger and Mono are selected. Cropped to Simpler; other window areas are omitted. Musical beat divisions and the warp algorithm are separate settings, even though both use the word “Beat.”

Region divides the available time into an equal number of pieces. Set Regions to 8 for the worked example. It gives everyone the same eight addresses without depending on attack detection. On this evenly warped one-bar selection, those pieces occupy eighth-note positions. On unevenly warped material, equal source-time regions need not match equal musical beats.

These are schematic boundaries, not a waveform traced from the Core Library loop. Transient asks where attacks occur; Beat asks where musical divisions fall; Region asks how to divide the available source time equally. Beat and Region agree in the illustrated evenly warped bar, but they answer different questions.

Double-click a boundary to delete it or double-click between boundaries to add one; drag a boundary to move it. Manual slicing is useful when a phrase begins before its loudest attack. Make a separate version before changing the eight-region exercise, because moving boundaries changes what its slice numbers mean.

Live 12.4.15: the exercise uses Slice By Region, Regions 8, Playback Mono and Gate. The fades display 0.00 ms in and 4.99 ms out: approximately the 5 ms starting point in the text. The available first bar is yellow; excluded audio is gray. Cropped to Simpler; other window areas are omitted. These fixed boundaries serve both MIDI patterns.

For an attack that sounds late, compare the MIDI note’s start with the audio inside its region. The note might be exactly on the grid while the drum begins slightly after the region boundary. Moving the MIDI note and moving the slice boundary solve different problems. The first moves the entire fragment in time; the second changes how much of its lead-in you hear.

5. Play the eight pieces in a new order

Live maps the first slice to C1, MIDI note 36, then continues chromatically: C♯1, D1, D♯1, E1, F1, F♯1, G1. These are selection keys. Calling the third slice D1 says nothing about the pitch of the drums inside it. Audition the eight keys once, slowly, before drawing notes.

The addresses for this eight-slice Simpler instrument. Keyboard note names differ across music software; use the MIDI numbers 36–43 when comparing systems. Within this lesson, numbered slices, note-editor rows and the printed rhythm all refer to the same eight source regions, in their original left-to-right order.

Create a one-bar MIDI clip. Set its grid to 1/8 and draw slices 1–2–3–4–5–6–7–8, one on each eighth. Use eighth-note lengths. Choose Gate for this exercise so note endings can create silence. Set Fade In to 0 ms initially and Fade Out to 5 ms as a listening starting point.

Reference rhythm: eight eighth-note gates, each triggering the next numbered slice. This original control pattern describes your MIDI performance, not a transcription of the break’s kick, snare or hi-hat parts. With the same warped region and slice settings, it gives you a useful baseline before rearranging the addresses.

Play the reference against the source, one at a time. Check whether it retains the bar’s order; listen for edge changes from fades and retriggering.

Live 12.4.15: Reference 1–8 plays MIDI notes 36–43 at beat offsets 0, 0.5, 1, 1.5, 2, 2.5, 3 and 3.5, each lasting half a quarter-note beat. The card stacks two cropped halves of the same one-bar editor so the note labels remain readable. Other window areas are omitted. The ascending rows select successive slices rather than a rising drum melody.

Duplicate the clip. Change the duplicated clip’s grid to 1/16. Keep the other notes two grid cells long, but make the two D1 notes at 2 & and 2 a one cell each. Now draw 1–3–5–3–3–1–7–rest–8. Place the attacks at 1, 1 &, 2, 2 &, 2 a, 3, 3 &, and 4 &. The two repeated slice-3 notes are sixteenths; the other notes are eighths. Leave beat 4’s first eighth empty. Keep velocities equal so you can focus on the new slice order, entrances and gate lengths without also changing dynamics.

Live’s ruler uses bar.beat.sixteenth: 1.2.3 means bar 1, beat 2, its third sixteenth — our “2 &.” The following 1.2.4 is “2 a.”

The complete flip: slice 1 on beat 1, slice 3 on 1 &, slice 5 on beat 2, slice 3 on 2 & and 2 a, slice 1 on beat 3, slice 7 on 3 &, an eighth rest on beat 4, then slice 8 on 4 &. All durations total one 4/4 bar.

Count the repeated notes using The Sixteenth Note: “2 & a.” Keep tapping quarter notes as the last slice arrives between beats. The Syncopation handout trains that disagreement between steady pulse and displaced emphasis.

Read horizontally for time and read each number for the source address. The narrower boxes hold the two sixteenth-note repetitions of slice 3, at 2 & and 2 a. The rest means no new trigger. With Gate selected, listen for whether the preceding note’s ending leaves an audible space; an empty MIDI grid alone does not demonstrate silence.

Listen to four repetitions. Does the doubled slice feel like a useful stutter or an accidental hiccup? Keep it only if it supports the pulse. Then try moving one entrance by a sixteenth, as the 16-step drum worksheet moves individual strikes while keeping four beats steady. Preserve a copy before each experiment.

Live 12.4.15: the flip uses slice addresses 1, 3, 5, 3, 3, 1, 7 and 8. Highlight 1 marks the D1 sixteenths at 2 & and 2 a; highlight 2 marks the empty first half of beat 4 before the final G1. Two cropped halves of the same editor are stacked; other window areas are omitted. With Gate and the short fade selected, check whether you hear the intended gap; the image establishes note placement, not audible silence.

To hear Gate versus Trigger clearly, temporarily shorten the slice-7 note at 3 & to a sixteenth. Compare whether Gate cuts the sound near 3 a and whether Trigger sustains it to the slice boundary at beat 4; the source may already have decayed. Restore its eighth-note length afterward.

Once the rhythm works, try lowering just the second slice-3 repetition. Velocity can alter Simpler’s level when its velocity response is enabled. If you hear no difference, check Simpler’s Vol < Vel control; it is set to 35% in these device screenshots. Raising it makes velocity affect level more strongly.

6. Move to Drum Rack when slices need separate treatment

Stay in one Simpler while choosing an order: its shared controls keep the experiment simple. Move to Drum Rack when one piece needs its own effect or level. Duplicate the instrument track first, then right-click Simpler’s sample display and choose Slice to Drum Rack. This replaces that Simpler with a Rack of its slices.

Live 12.4.15: the actual waveform context menu reads “Slice to Drum Rack,” followed by “Slice to New MIDI Track.” The first replaces this Simpler; the second creates another track. Use the first command on your duplicate track to preserve the original Simpler version. Cropped from the full-screen capture to the menu and device; the surrounding Session grid and other window areas are omitted.

The audio-clip command Slice to New MIDI Track also builds a Rack, with options for divisions and slicing presets. It differs from Convert Drums to New MIDI Track, which analyzes rhythms to trigger other drum sounds. Slicing retains chunks of your recording. Compare these operations in the manual’s audio-to-MIDI chapter.

Live 12.4.15: eight occupied pads and their expanded mixer chains confirm the conversion. Slice 1 is selected; the receiving notes run from C1 to G1. Highlight 1 shows choke group 1 on every chain, keeping the slices mutually exclusive here. Two crops from one capture are stacked; other tracks and empty window areas are omitted. The contained Simpler is not open in this view.

One Simpler’s Mono playback interrupts previous slices globally. Separate Rack chains can overlap unless you manage their behavior; Drum Rack choke groups can make assigned chains silence one another. Here all eight chains use choke group 1, so they remain mutually exclusive. Listen again after conversion. Do not assume a matching note pattern guarantees matching tails. Our hip-hop guide puts this kind of repetition into a wider beat-making context.

Select Slice 3, open its device chain, and place an EQ after that slice’s Simpler inside the Rack. Compare a small high-frequency cut with bypass. Trigger Slice 1 and check whether its sound stays unchanged while you bypass the EQ on Slice 3. An effect after the entire Rack affects every slice. For example, try a high shelf around 4 kHz, down 3 dB; treat that as a listening starting point.

Live 12.4.15: Slice 3’s selected chain contains Simpler followed by active EQ Eight. The detail shows a shelf cut; the knob panel displays 1.00 kHz and 0.00 dB, so it does not verify the recommended shelf values. Two crops omit other window areas.

Compare the device activator with the bypassed state; judge the sound yourself.

Live 12.4.15: the same Slice 3 EQ is bypassed: its activator and curve are gray. Two crops omit other window areas. This is a device-state comparison, not an audition result.

Select another pad to inspect which devices belong to that chain.

Live 12.4.15: Slice 1 has its own Simpler followed by an empty effects area. The EQ on Slice 3 is outside this selected chain. Two crops omit other window areas.

Use the routing map to distinguish a chain effect from a shared Rack effect.

Routing schematic for the per-slice experiment, not a capture of an inserted effect. Put EQ Eight after Slice 3’s Simpler inside that chain; an effect outside and after the Rack processes all its slices. Compare bypass on Slice 3, then play Slice 1 and check whether its sound stays unchanged. The diagram establishes routing, not an audition result.

7. Resample the flip and keep the editable version

Printing records the sound of the performance, including processing on the chosen route. For one track, create an audio track and choose that source in Audio From. Post FX includes its device processing; Post Mixer also includes its mixer adjustments. For the whole audible mix, select Resampling, which records Live’s Main output.

Choose the recording point deliberately. A track-to-track Post FX print excludes that source track’s mixer adjustments; Post Mixer includes them. Resampling captures the Main output instead, so unrelated audible parts, return effects and Main processing can become part of the new recording. The diagram shows routes, not a screenshot of Live’s routing controls.

For this exercise, stop other clips and mute the reference and study tracks. Play only the flip. Check the Main meter before recording and lower the contributing signal if it clips. Resampling commits that signal, including Main processing. On the print track, choose Resampling and set Monitor Off. Set Global Launch Quantization to 1 Bar.

Live 12.4.15: Print is prepared with Resampling, Monitor Off and its arm control off. The upper crop shows 1 Bar launch quantization. Empty middle rows and other window areas are omitted; no active recording or meter level is evidenced.

Arm the print track and click the record circle in an empty Session slot. Once recording begins, count two bars; during the second bar, click that clip’s launch button to finish recording and enter playback at the next quantized boundary. Stop the MIDI source before auditioning the print. Keep the clip’s launch quantization set to Global for this exercise. This is launch timing, not MIDI Record Quantization.

Live 12.4.15: Print receives Resampling with Monitor Off. Highlight 2 identifies the clip start/end fields: 1.1.1 to 3.1.1. Highlight 3 identifies loop Position and Length, currently two bars. To keep the first pass, change End to 2.1.1 and Length to 1.0.0; this screenshot still shows the two-bar state. The lower panel shows its stereo waveform. Three crops from the same capture separate routing, loop controls and audio for readability; other window areas are omitted. Audio remains beyond the loop brace. Inspect the return to the first beat by ear before another chop.

After recording, disarm the print track. Audition both passes and choose one complete bar. In Clip View, set the loop position to that bar’s downbeat and its length to 1.0.0; set the clip’s start and end to the same bar boundaries. Loop it several times to check the join. Drag this prepared clip into another Simpler and confirm that its available region is exactly one bar. These marker edits leave the underlying recording intact. For the first pass, use start 1.1.1 and end 2.1.1; for the second, use 2.1.1 and 3.1.1. Keep the editable track. Use Collect All and Save when gathering media.

Live 12.4.15: marker-selection example using the original Core Library file, not a newly recorded flip. Start/end and loop controls select one bar. Two crops omit other window areas.

Compare that selection with the available region in Simpler; audition the join yourself.

Live 12.4.15: the same source-region example in Simpler shows the first bar available and the remainder excluded, with Warp set to Beats and as 1 Bar. Cropped to the device. This does not document dragging or auditioning a new print.

8. Fix edges, check the groove, then stop editing

A click at a boundary suggests an abrupt waveform change. Try moving the boundary slightly or adding a short fade, then listen again; excessive Fade In can blunt a drum attack. Cycling ‘74’s amplitude tutorial explains why gradual signal changes help avoid clicks.

Four checks before committing another generation: verify both ends of the bar, hear the slice boundaries, compare the tails against the next entrance, and audition one version at a time. Each pair separates a useful musical change from an accidental playback or routing problem; the checklist applies to both the Simpler and Drum Rack versions.

If the rest still rings, check Gate, release or Fade Out, and any effects tails. If a hit disappears, inspect its slice start before boosting gain. Finish when you can clap the new entrances and explain which two changes made the groove work. A Tissimo music production teacher can help you compare the original timing with your flip in a live lesson.

Repeat the bar four times and vary the fourth ending. Our home production guide helps develop the loop into a project; the piano-roll-to-staff guide connects MIDI timing with notation.
