Ableton/Live/UG/31 Instrument Reference/13 Wavetable/07 MIDI Tab
- MIDI sources in their own matrix:

- Velocity and Note — held for the note. Note is centered on C3, so Note at 100% on Filter Frequency makes the cutoff follow the played note.
- Pitch Bend, Aftertouch, Modulation Wheel — controller sources, also reachable with clip envelopes.
- Random — a new value per note.
- Rows are shared with the Matrix tab.
