Default MIDI Pitch shift?

Hey guys!

I want a note to gradually (over 1 beat) change pitch to 1 octave lower (like a whammy bar dive on a guitar). How do I set it?

pitchbend messages. lots of them for smoothness.

This can only work if your instrument supports it. Many instruments are fixed to a pitch bend range of two semitones. What you need to do is set the pitch bend range to an octave if that's possible in yours and then just use your pitch wheel and record it or draw the messages into the MIDI editor (or use ReaControlMIDI and a track automation curve).

If your instrument doesn't support setting the bend range to an octave you won't be able to do it in the MIDI domain. In that case you could try bouncing the note to audio and use a take pitch automation envelope to do your dive bomb.

Actually, to be precise: the pitch bend range only needs to go as far as ±6 semi-tones for a bend of a full octave. You would transpose the note by -6 semi-tones, start playing with pitch bend at +6 (so it would start at the intended note) and then gradually lower it to -6.

(Iirc, I did this a lot with a Roland JX-8P, which only goes as far as ±7 semi-tones.)
