[sdiy] Doepfer REVerb module

[Ullrich Peter]

Hi Michael!

Maybe it is the Wavefront chip that is used: http://www.wavefrontsemi.com/products/AL3201pop.html
together with ADC and DAC.

Also used for this synth from Carsten Tönsmann:

Ciao
Peter

Karl, thanks for that (unintended) pointer!
I read about the A-187 but didn't see this lines on the *cough* doepfer, page:

 >>A ready made DSP board is used inside the A-187-1 module. Consequently only these effects and parameters are available that are supported by the DSP module. Some parameters can be changed only in steps or with audible artefacts. The DSP board has 20 Bit DA and AD converter with 32 kHz sample rate available. The inter sound processing uses 24 Bit.<<

I can't answer your question but I'm  particularly interested in that pice of hardware since till now I planned to use the guts of a stomp-box (see below).
That paragraph above smells a lot like as if application examples have been used of that particular unknown dsp vendor.

Ripping that board out of a bought A-187 is no option, it's way too expensive in that context.
