Hey there,
regarding the new accompaniment feature in the revo ARP:
The octave setting doesn't have any effect when accompaniment mode is checked.
Notes are played back (and shown on the virtual keyboard) very low.
I believe they are always playing in the C1 octave. (No matter where I play notes on my keyboard.
Even when I play very high notes/chords in the upper octaves I still only get low notes.)
Best,
tL.
