<DIV>I just finished one (of the many) AR envelopes, for the most part it's the Charles Broduer schematic. Consists of 2 diodes, 2 pots, a 741, couple resistors, and LED. I tended to avoid these designs but I'm expecting a MIDI to trigger board from Mr. Maddox and needed envelopes that would reflect the trigger velocities. </DIV>
<DIV> First problem was the envelope would slow up considerably when it gets close to zero. Not good for percussion. I fixed that by using an offset trim (striaght from TL071 data).</DIV>
<DIV> I've just started experimenting with the AR so if anyone has any opinions or suggestions or tips, please let them flow. Such as capacitor types ( found that polyester SEEMS quicker than the specified electrolytic ). I would like to tweak the response curves but not sure how to approach it.</DIV>
<DIV> Any techniques for employing velocity in patches would be very interesting to hear about.</DIV>

<DIV>Thanks,</DIV>
