"There is some more work to do and I need help how to do it.
1. I'll change 40106 for BC547 in GATE OUT. No help needed :)
2. How to make 16 steps? Single switch 2x8/1x16 needed. There is unused 4001 left, and I can manage to build logic with unused 4520Q3. But how to link CV2 to 1 and GATE OUT2 to 1? Or maybe there is other option?
3. Can 555 handle 12V? I'd like to run all from +12V.
4. Portamento seems to work even when it's OFF. At the moment caps are 22uF and seems to be too large (portamento is too long), but will change to 2u2F, maybe even less. Will report after try.
"This synth is open source, and the source code is included in the same package. It comes with an easy waveform editor that lets you create entire new banks of waveforms while you test the sound of them. These new banks can be imported into 8 slots per oscilator, this means that you can have up to 16 different banks giving you more than 1000 waveforms to toy with. The synth is configured to have the same 8 banks in both oscilators. But it doesn't stop there.
The synth has also 9 different filters that processes the oscilators. The synth is relatively low on the cpu side, and it is configured to withstand most cpu spikes. When a voice (16 total) is not in use then it goes to sleep freeing up further more cpu."
"Awesome set-up of Cwejman gear from the music project Odyssey of a G. S1mk2, Eurorack modules housed in Cwejman cases and sequencing provided by a Roland MC-4.
"CONDOR RSM BY INNOVEX, A HAMMOND COMPANY. A MULTIVIDER, this unit was designed to produce harmonics at the touch of a button. IT WAS USED By running the pickup from A tenor saxophone into it. Imagine taking a real low note from a Tenor sax, then add a sub harmonic or two. Or, take a note and go up a couple of octaves. It has presets for Repeat, Attack, Vibrato/Tremolo, Sub Octave, Dynamute, Fuzz, Bass Sax, Tuba, Bass Clarinet, Bassoon, English horn, Cello, Natural Amplified, Horn, Oboe, and Soprano Sax. The slide Pots on the top are for; Intensity for Vibrato and Tremolo, Rate for Vibrato/Tremolo Repeat and Dynamute, Tone (Bass or Treble), and Volume for the associated Presets. Hammond is the Company that made the best Electronic Organs on the market. This unit gives you the ability to use the controls that you would find on a Hammond Organ for your pickup or microphone."
"Rare, hard to find Model 64 Sequencer cartridge for Commodore 64/128 computer systems by Sequential Circuits, Inc. This MIDI interface has a basic sequencer built into ROM, which can be bypassed after the software has loaded."
Update via Aud1073cH in the comments: "I believe this was the flagship controller that went with the Sequential MAX. The printing on the MAX said 'MIDI voice expander computer peripheral'"
