MIDI controllers

A major limitation of MIDI is the nature of controller information. With the exception of poly pressure, controller messages are channel-specific messages, i. e., they affect the entire instrument, regardless of whether they are inserted for a part or a note.

Therefore, when using Note Expression with MIDI instruments (hardware or VSTi), it is important to understand that articulation data on one note usually also affects all other notes of the same voice, i. e. any other note playing on the same channel at the same time. This limits the potential of Note Expression for MIDI controller events to monophonic (solo) performances. When using MIDI controllers in polyphonic performances, we recommend using controller lanes in the Key Editor.

However, Note Expression can be useful in the context of standard VST instruments and MIDI hardware instruments.
