Yamaha CS-5, Vintage Analog Synthesizer

via this auction

"A very cool monosynth. It has a multimode filter, trigger in (for following audio, trigger sends, etc), CV/Gate, etc etc. It's in very good shape with minimal wear and it functions perfectly fine. Sounds distinctly better to me than other black Yamaha CS line synths (CS-15, CS-30) for some reason..."

According to the auction this is the one at the PNW Synthfest in this video.

Doepfer MAQ16/3 MIDI Analogue Sequencer - 49 knobs of pure joy

via this auction
"- has both MIDI and CV, so you can control everything from modular and analogue gear to midi hardware and softsynths. 3 independent channels of CV and gate/trigger outs, so you can run 3 synths, or use two to modulate one row, or get creative and have everything modulating everything else. That means you can have the values of one row affect the timing of another, and the values of that row affect the pitch of another. Furthermore you can then use external midi to transpose those sequences. independent time signatures, loop points, and start points, all off the same clock"

MacBeth Vortex in the Making

Pics via Ken MacBeth on Facebook

Top: "I just etched the Jackfield PCB for the Mk1 Vortex proto #8- it takes a nice picture! Now to drill the darned thing!"

2nd: "This photo shows the 8th prototype in the micromac/Mk1 VORTEX unit- no rotaries fitted- but this is the essential sound engine that I intend to try out shortly. It is the 'cleaned up' version of prototype #7 that you may have seen demonstrated in videos that I did!n Please see other pic for Filter/VCA detail!"

3rd: "An important part of the VORTEX tone and character come from the filter and VCA- the USE of a selected CA3046, BC549Cs and a CA3080 based VCA make this synth have the character of the Multimoog/Source like sound"

bottom: "Here's a pic, front and rear, of the Mk1 Vortex Jackfield (prototype)- things finalize tommorow for the whole unit!"
