Re: BPM & Pitch Shift on Repeater

Jeremy - 

A similar idea (tracking the values with a sequencer) occured to me last night - I won't have an opportunity to try this for a few days, but will let you know when I do.

If the Repeater sends out CC14 and CC46 when you adjust pitch/BPM (CC9 and CC41 when adjusting tempo) it should be the same value in as CC to produce the same result.
