I wanted to create the kind of envelope (a simple AR to begin with) where the attack and release times change every time the envelope gets triggered. In my attachment you can see that I tried to realize this with a randomly changing duty-cycle value.
Because I wanted the same random dc-value for the attack and release time, I placed the expression "(!BPM nextRandom) * !DCRange + o.5" into the value field of a constant, which I then pasted into the attack and rel. time fields of the envelope. The desired effect was not audible (attack and release being rather static, non-varying).
Is this because a "constant" might not be able to interpret a "!BPM"-function?
Thanks.

p.s. any news about my motor mix replacement unit?

(!BPM nextRandom)

is not what you want. The nextRandom function requires a trigger as its first argument. If you would like a "metronome" trigger, try

(1 bpm: !BPM) nextRandom

This will give you a random value between -1 and 1 on every beat at the tempo of !BPM. To restrict this to just positive values, use

(1 bpm: !BPM) nextRandom abs

Of course! I already used this expression once before. It must have slipped my mind. Anyway, it works...with every trigger a different "wave", beautiful.
