The MIDI Sculptor is a Max for Live device for Ableton Live that makes it easy to create variations of MIDI clips with tools to modify pitch, velocity, and timing.

1. Download Sculptor.amxd v2.0 beta 2 for Live 11
   • Or Download Sculptor.amxd v1.1 for Live 10
2. Drag the Sculptor.amxd device onto any MIDI track
3. Click the "Sculpting Tools" button to open the main UI in a window
4. Adjust the zoom level as desired
5. Open Live's Info View and hover over any control for documentation

Some of the things you can do with this device:

• Randomize the timing and velocity of notes within a controllable range.
• Strum chords by making simultaneous notes play in quick succession.
• Compress velocity ranges to tame wild recordings with notes that are too quiet or too loud, or spread the velocities farther apart for more dynamic range.
• Reverse all the pitches without changing timing or velocity.
• Randomly swap notes in a drum rack clip for sonic variations with the same timing as the original.
• Randomly delete notes to "thin out" a clip to create lower energy variations.
• Randomize in all sorts of ways to experiment and overcome writer's block.

• The "Sculpting Tools" button opens the main UI in a floating window (always on top of Live), so you can jump between different clips and keep editing.
• The UI is zoomable for high resolution monitors.
• Sculpting operations apply to the selected notes of the clip, so you can control what's affected.
  • Note: If nothing is happening, it's probably because you only have one note selected.

• Operate on the pitch, velocity, start time, or duration of the selected notes.
• Set a maximum range of the operation.
• Shift moves the chosen note property in the positive or negative direction
• Randomize moves the chosen note property in a random direction by a random amount (within the chosen range)
  • Every time you use the randomize X-Y pad, a new random value is chosen for each corner. You can "scrub" around looking for sweet spots. Once you let go of the mouse, new random values will be chosen.
• Spread spreads the chosen note properties closer together or farther apart.
• Edge behavior (the 4 buttons in the lower left) determines what happens when a note hits the minimum or maximum value:
  • Clamp holds the note property at its minimum/maximum value
  • Reflect "bounces" off the edge and moves in the opposite direction
  • Wrap wraps around from the minimum to maximum value and vice versa
  • The "keep going" option lets notes move off the edge of the clip and removes notes with negative velocities or invalid pitches
• Spread anchor behavior (the 3 buttons in the lower right) controls the spread operation:
  • Lowest: don't move the note with the lowest value
  • Middle: don't move the note with the average value. In other words, spread away from / towards the center.
  • Highest: don't move the note with the highest value

A Strum option in the Slide Tool moves notes based on their relative pitch.

• Strum the start or end time of notes.
• Lock the duration or end position.
• Anchor to the lowest or highest note, or strum around the middle.
• Change the tension to accelerate or decelerate the strum.

• Operate on a combination of pitch, velocity, and duration. Start times do not change.
• Rotate copies the chosen note properties from one note to the next while keeping the start times the same. The rotation wraps around the end of the clip.
• Randomly swap the chosen note properties while keeping the start times the same
  • Every time you use the randomize X-Y pad, new random swap targets are chosen for each corner. You can "scrub" around looking for sweet spots. Once you let go of the mouse, new random targets will be chosen.
• Swap the chosen note properties between consecutive pairs of notes.
• Reverse the chosen note properties across the notes (e.g. the last note gets the first note's pitch and vice versa)
• "Zip" the chosen note properties by splitting the list of notes into two halves and interleaving the halves.

• Randomly delete, mute, or unmute notes for "thinning out" a busy clip
• Set the chosen pitch, velocity, start time, or duration on a random set of notes
• Set the chosen note property to the chosen value value on all the selected notes
