Thanks to both of you.
I didn’t try the MULTI ENV as the manual implies it’s only working for monophony. Anyway, i tried, and couldn’t firgure out how it’s supposed to work. I can only hear the SUS working, and acting as a global attenuator. A, D, and R seem to have no effect.
I’m curious to know what’s meant by “on top of the tracks enveloppes”. Are the parameters added to the track’s ones, or is it “on top” from the amplification level ? Anyway, i couldn’t understand what it’s doing, despite my (infinite) knowledge and (massive) experience !
I’ll check the LFO trick as well, even if losing a LFO does matter quite a lot.
EDIT : regarding MultiMode. I need to use the Multimode MIDI channel ! Further test results will be posted here.
