I want to set up instruments with unconventional key-mappings. Eg, map MIDI input note C to trigger an E; input note F to trigger an Eb; Bb to trigger a D, Eb to trigger a Db etc. So that if I play the bass of a cycle of fifths, it automatically plays a chain of voice-led thirds alternating with sevenths. Various things like that that are a bit more complex than simple transposing.
In all other respects I want the instruments to just react like normal: normal velocity response, MIDI cc control etc.
Can I do this in JABB?
If not, can I do it by loading the JABB instruments into Kompakt or Kontakt?
