WFM oscillator -LA67 & Rebach VCO-A,VCF-A,ADSR-A

Dziam Bass

"Hello all.
today I patched WFM oscillator from LA67 and Rebach VCO-A, VCF-A ADSR. I added a traingle wave to FM IN in WFM and pulse waves from WFM to PWM IN in VCO rebach.
as you can see nice nice analog sound when i open more and close the filter.
This is a nice combination for me because the WFM is based on the old 1970 KOBOL oscillator and the rebate VCO based on the AS3340 so it gives a great character,
I tried to subtly add FM and open the filter for a musically working sound."

Interesting look at the buttons under the membrane panel.

"Although the switches have not been cleaned, the board is in overall working condition, with both the coil and vacuum display working, this should fix an 8P that's not lighting up, but otherwise working."

"I bought this unit only recently to integrate with my Moog semi-modular setup, mostly as an additional voice to integrate with Mother 32. Its a fantastic box all by itself, and honestly i think it is probably superior to the Mother in many ways (i like the flexibility of the voice way more than the Moog, esp its FM capabilities) but i am finding it mostly overlaps too much with other things i already have.

*again, 1 detail about this unit worth flagging is that the right wood side panel is a bit wiggly. Apparently, this is a common problem with these boxes, and can be fixed, but i haven't had it long enough to bother. It is not an issue if its just sitting on a desktop, in which case it is rock-solid and unnoticeable. Just FYI."
