Pro Tools provides MIDI Editor windows for detailed MIDI editing.
MIDI Editor windows display and let you edit MIDI data (notes, velocities, and continuous controller data) for one or more MIDI or Instrument tracks. When displaying multiple tracks in a MIDI Editor window, MIDI notes from different tracks are superimposed. MIDI Editor windows can also show Auxiliary Input tracks.
Velocity, other continuous controller data (MIDI and Instrument tracks), and automation data (Instrument and Auxiliary Input tracks only), can be edited along with MIDI notes and appear in
Controller lanes under the Notes pane. Velocities for MIDI notes on multiple tracks are also superimposed in the Velocity lane. However, for all other automation and controller data, additional lanes are shown for each automation or controller type for each track.
For example, if two Instrument tracks are shown in a MIDI Editor window, the MIDI notes for each track are superimposed in the Notes pane and the velocities for each track are superimposed in the Velocity lane. However, you would see two Mod Wheel Controller lanes, one for each track; and you would see two Volume lanes, one for each track.
