Ableton Live 12's MIDI Transformations, explained

MIDI Transformations reshape notes you've already written, unlike a MIDI Generator, which creates new notes from nothing. Live 12 has 11 native Transformations plus Velocity Shaper, a bundled Max for Live tool — 12 in total, covering everything from arpeggiation and strumming to MPE pitch-bend curves.

This guide covers four of the most useful Transformations in depth — Arpeggiate, Connect, Ornament and Strum — then runs through the rest, using the companion video below (which also covers MIDI Generators — see that guide for those).

What you need

Unlike the MIDI Generators, which are uniformly Standard+Suite, one Transformation breaks the pattern: Quantize is Live's long-standing quantize feature, reimplemented as a Note Transformation, so it's available in every edition including Intro.

How Transformations work, in general

Select the notes you want to change (or make a time selection, or leave both empty to affect the whole clip loop), open the Transform panel, and pick a tool, as the MIDI Tools chapter of the Live 12 manual documents in full. With Auto Apply on, changes happen live as you adjust parameters; turn it off to preview settings and commit with Apply (or Ctrl/Cmd+Enter). Undo in the Edit menu reverts note changes; Reset only resets a tool's own parameters, not the notes.

Arpeggiate

Arpeggiate splits a note selection into an arpeggiated pattern, built on the same engine as the Arpeggiator MIDI effect.

• Style picks from the same 18 pattern types Arpeggiator offers.
• Distance sets how far each step transposes, in scale degrees or semitones depending on whether a scale is active; Steps sets how many transposed steps the pattern uses.
• Rate sets the pattern's speed (and note length); Gate shortens notes below 100% or lengthens them above it.

Connect

Connect fills the gaps between existing notes with new, interpolated notes — useful for turning a sparse melodic idea into a fuller line without manually drawing every note.

• Spread randomizes the pitch of connecting notes around the originals.
• Density sets what percentage of each gap gets filled; at 100%, every gap between existing notes is filled.
• Rate sets the interpolated notes' length, and Tie sets the probability that a generated note extends all the way to the next original note.

Ornament

Ornament adds Flam or Grace Notes to the start of selected notes — reapplying it stacks on more.

• Flam adds one note before each selected note. Flam Position (as a percentage of the current grid) sets whether it replaces the start of the original note (positive values) or sits before it (negative values); Flam Velocity sets its relative velocity.
• Grace Notes adds multiple notes of equal length before each original note. Grace Notes Pitch (High/Low/Same) sets their pitch relative to the original; Position, Velocity, Chance and Amount control placement, dynamics, probability and how many grace notes are added.

Strum

Strum offsets the start times of notes in a chord to sound like a strummed instrument instead of a stacked hit.

• Strum Low offsets note start times beginning with the lowest note; Strum High does the same starting from the highest note. Both need a non-zero value for the Transformation to have any effect.
• Tension reshapes the spacing between notes along a curve instead of evenly — positive values front-load the spacing and taper it off, negative values do the reverse.

The rest of Live's MIDI Transformations

• Quantize moves or stretches note start and/or end times to the grid or a specific meter (including triplets). The Amount control allows partial quantization — moving notes only part of the way to the grid, rather than snapping them rigidly. It's available in every Live edition, including Intro.
• Chop divides notes into up to 64 parts, with a Gaps system for adding rests into the pattern and Emphasis toggles for stretching specific notes or gaps longer.
• Recombine permutes note Position, Pitch, Duration or Velocity across a selection, using Shuffle (random), Mirror (reverse order) or Rotate (circular shift) — individually or combined.
• Span reshapes note duration using three articulation types: legato (extends each note to the next note's start), tenuto (preserves length) and staccato (shortens notes based on the smallest gap between starts).
• Time Warp applies a speed curve, with up to three breakpoints, to selected notes — for accelerando, ritardando or other tempo-feel changes within a fixed part.
• Glissando and LFO are MPE-specific Transformations: Glissando connects one note's pitch to the next along a pitch-bend curve, and LFO modulates pitch bend, slide or pressure with an oscillator. Both are visible in the MPE Editor's expression lanes.
• Velocity Shaper is the bundled Max for Live Transformation (alongside the Euclidean Generator): it reshapes note velocities using a drawable, loopable envelope.

Frequently asked questions

Are MIDI Transformations available in Ableton Live Standard?

Most of them, yes — Arpeggiate, Connect, Ornament, Strum, Chop, Recombine, Span, Time Warp and Velocity Shaper are all in Standard and Suite, not Intro. Quantize is the exception: it's available in every edition, including Intro, since it's Live's existing quantize feature folded into the new Transform panel.

What's the difference between a Transformation and a Generator?

A Transformation reshapes notes you've already selected and needs existing notes as input. A Generator creates new notes from its own parameters and doesn't need a selection to start from.

Does Quantize work differently now that it's a Transformation?

No — it's the same Quantize feature Live has always had, now exposed as a panel among the other Transformations (and reachable the same way as before via Edit menu → Quantize Settings, or Ctrl/Cmd+Shift+U).

What's the difference between Flam and Grace Notes in Ornament?

Flam adds a single note before each selected note. Grace Notes adds multiple notes of equal length before each one, with their own pitch (higher, lower or the same as the original), placement and probability settings.

Can I use Arpeggiate's patterns outside of the Arpeggiator effect?

Yes — that's exactly what the Arpeggiate Transformation is for. It applies the same 18 style patterns as the Arpeggiator MIDI effect directly to a note selection, without needing to keep the effect on the track.

Is Velocity Shaper a native Live device?

No. Like the Euclidean Generator, Velocity Shaper is a bundled Max for Live MIDI Tool — installed by default with Live Standard and Suite, and, because it's Max for Live, editable in a Max patcher if you want to customize it further.
