Thanks for your quick reply, Alan
If assigning the FS2 parameter to Mod wheel as you suggest, will the changeover from slow/fast and fast/slow incorporate the ramp up/down times, which I presume are pre-set ? This would be the most authentic way, I think.
As you didn't mention anything about the brake function, am I to presume this will only work using the footswitch ?
It would be great to have it respond just to cc 0 or 1 and ramp up/down to chorale or tremolo when moving the mod wheel. If it doesn't work that way now, could it be done in an update, perhaps ?
Again, thanks for any info.
