I can't help myself...

There's a bit more information included with the photos.

What does it sound like?

Well I guess it still sounds like a Micro-preset but with just a whole lot more control. The basic filter design is more or less the same but I added the VC-Q part from a PS-3100 to allow me to vary the resonance from the new front panel.

The additional electronics in there is for a beefier power supply, the two new EGs and VCO output buffering for the Synthe section. The empty op-amp socket is for further additions that may or may not be added at a later stage.

I'll pop some sound samples up at some point.

Sounds great Tony. Very Happy

I always loved the little Micro-preset. I unfortunately had to part with mine as I needed to pay some bills. Instant "OMD" as they say! Smile

Tony,

do you happen to have schematics for the Micro Preset? I have this partly working Micro Preset that I would like to restore, but I was not able to find any readable schematics.
It would be great if you could help me - the little bugger sat in the closet for far too long.
