Suppose I want a single envelope to control both VCF and VCA. This is the way it works on synths like the Roland Juno. I’d like to get the same effect with OBXd. Of course its not as flexible as having two envelopes, but easier to control. Pretty much every synth now has two separate envelopes, so you need twice as many sliders.
In the Zynthian UI I can use MIDI-learn to bind a slider to say “Attack”, but if I then bind the same slider to “FilterAttack” it cancels the previous binding. So it looks like only one parameter can be attached to each CC.
One workaround might be to duplicate the control message on another CC channel, which could be bound to another parameter. But I can’t figure out how to do this. If the “MIDI CC Map” effect had a “duplicate” option this would be useful. That is, to send on the remapped CC as well as the original CC.
I tried cloning the MIDI messages to another channel, and remapping that channel, and then sending both this and the original to the synth, but no amount of tweaking seemed to make this work. What is the difference between “Clone MIDI to…” and “MIDI Routing”? Both would seem to offer the option to send midi to another channel, but they don’t work the same way.
