I just put this up over at Prodigy-Pro and thought it might also be of interest here.

I honestly didn't think anyone remembered or used the MicMix Dynaflanger anymore. I designed it in '77-78 after pickup up Bill Hall's concept for it. Then I got this in another thread:

Totally off topic...

mediatech,

You worked at MicMix? I'd kill for dynaflanger schematics. I don't know why, but there's a certain thing that the envelope follower does for a couple of things... high hats, barky guitars, you know. It's hard enough to find one to buy, so it's something I'd consider putting together.


Well aurt you won't have to kill for them after all. Been lookin' for them all day. Here's the block diagram:

The schematics, in four tiles, are each about 4 Mbytes:

Note the Wilson current mirror at the output of the SAD1024. It really lowered distortion and increased headroom. I think, don't remember the level and frequency, that it went from 3% THD to 0.8%.

If I had to do it all over again I would put an exponential converter ahead of the high frequency VCO clock generator. It makes the frequency and envelope tracking a little more musical. I did it for a SSM2040-based phaser and a stereo synthesizer and it was far more musical and adjustment was less touchy.
