"The DS2 was a very popular synth for performance and studio work. The CRUMAR DFS2 has dual oscillators, filters, Noise generators, EQ, Pitch, ASDR sections and a weird sequencer thingy, too. It's very well built and roadworthy. Your favorite '80s disco hits were played using these things. You can do white or pink noise sweeps - all those tacky tricks."

thanks mystery person!??!
please get in touch? any info anyone?
it has a paia midi2cv8 set to MIDI CC mode w/ buffers and atten on each two cem 3394 Synth Voices - vco/vca/vcf x 2 noise source a lag/lfo vcs type thing a cosine/sine quadrature lfo modular opamps inverters mixers banana to 1/4"
all diy except the paia midi2cv8 sequence is from cgs seq switch sequencer not using the midi yet

Quick sample video of my work in progress. Has a 24 point RCA patch bay and a 4 in/out on off section. My next set of bends will be two pitch controls, momentary switches for the on/offs, and more accessible tone controls for the samples.
Also, tucked deep in the lab is a RZ-1 Plus that I'm working on."
Casio RZ-1 Drum Machine Circuit Bent Part 2 Finished
"Casio Drum Machine Circuit Bent Part 2 (Casio RZ1 RZ 1 RZ-1)
Has a 24 point RCA patch bay that short circuits three of the four eprom chips. The different chips are for certain samples, so some patches effect only certain sounds. You can patch with in the chips and chip to chip. In addition to the patch bay there are four input / output on/off switch section with toggle switches and momentary buttons.
There is now a switch to bypass the RZ-1s main timing crystals with two getlofi 1799 precision oscillators to allow for some great pitch control. I still have a little bit of tweaking to do with some different pots and resistors.
I've added 10k pots on the top to easier access the samples tone control. Also, I replaced the internal permanent soldered battery with a replaceable one.
