    Hi there,
    I have been rattaling my brain for a good few hours, but I cant come up with a solution. Basically I have a modulation matrix that has sources and targets etc. I have 4 targets which are Attack, Decay, Sustain and Release. Im wondering the best way to to modulate these parametres, and what is the best way to put into pratice. I just have 4 knobs attached to it at the moment.
    Thanks in advance.:)

    the most used modulation of these parameters is the pitch from midi pitch module. The midi pitch module sends values from 0 to 127.
    attack-, decay- and release-time require values from -20 to 80 (logarithmic scale).
    From knobs you use a fixed value of f.i. 10. So if you want to modulate this value you can add or subtract a part from midi-pitch:
    10 + a · pitch
    where a is a usefull value.

    Thanks very much for the reply.
    I have had a go at your technique and cant quite get it working.
    I think im getting confused on how to modulate things in the first place. I have just established that my LFO has an output of -1 to 1 and the speed knob ranges from 0 to 12. Im trying to modulate the speed by multiplying by 6 and adding 6 but it doesent work either.
    Do you have any suggestions on how to get these fixed? I have used the note pitch but as I said I cant follow it.
    Thanks very much.

    please post a simple example of your ensemble here.

    Im looking forward to learning this routing, too, I'm spending lots of time
    not quite figuring out how to modulate various parameters.
