HI, I have looked fruitlessly at commercial packages to no avail to help me do this: Is there any way it can be done as a macro in Reaper? I would like to generate a chord from a single note - BUT - I would like to be able to generate a different chord for each note of my midi keyboard? This is so that for example, I could have all major chords in my first octave, and say minor chords in the second octave and so on. Any help would be greatly appreciated Pootler
