1967 Moog Keyboard Schematic

via Mike Peake on AH:
"I've seen the note on Matrixsynth regarding the need for an archivist at the Moog Foundation, and that much of Bob's archives were discovered to be moldy, so I emailed them but haven't heard back. The thing is, I've got some original documentation in decent condition that I'm willing to donate if they want it.
I don't know if it's anything special or not, so I'm running it past you folks in the meantime, if anyone's interested in such things. I'll see if Mr. Luther wants it if the Foundation has no need.

For your enjoyment, if it's indeed enjoyable, just one of several 1967 "blueprint" schematics. Most are two to four page foldouts, and I only have a legal-size scanner at my disposal. I of course know that the Moog Service Manual (which is online) supercedes such things, but just in case this is interesting to anybody...

As always, click on "all sizes" for the large size.
Sorry, just this one as I don't know if they're that interesting or not.

Easier,

Yamaha CS15

"Monophonic, 2VCO, 2VCF, 2VCA, 2ENV, 1LFO synthesizer

It's actually a duophonic / bitimbral synth but you have to connect it to CV (Hz/V like Korg not V/Oct) to get the extra voice.

Each of the two VCOs has its own CV/Gate control.

The best things about it are the flexibility of the VCFs and the routings to the filters and envelopes.

You can rout VCO 1 to both VCFs and the VCFs to any of the envelopes positive or negative voltage.

The VCFs are 12 dB/Oct and are switchable between low, band or high-pass. They are the key to the nice sound of the Yamaha CS family.

Other nice features are noise, external-in for processing other sounds,

LFO with Sample & Hold for those bubbling sounds and an individual auto-bend for the VCOs."

RedSound Elevata

images via this auction
"16-voice polyphonic and has 8 multi-timbral parts. There are two analog modelling oscillators per voice with square, sawtooth, sine & formant waveforms. The filter is a 2-pole (12dB/oct) with switchable low-, high-, or band-pass modes. There are ADSR envelopes for the filter and VCA sections and two syncable LFOs with multiple waveforms. You will also find portamento, a basic arpeggiator, chorus and flange effects, and a joystick controller assignable to any modulatable parameter. There are no reverb or delay effects unfortunately.

Every parameter has a knob or switch just a hand-grab away, so creating sounds is quick and easy on the Elevata. The Sound Wizard is a cool function that randomizes various parameters. This allows you to experiment with creating random sounds, hopefully leading to some happy accidents! Your custom creations can be stored in any of 127 user patches. There are also 127 preset patches and 90 multi-patches (aka performances). The Multi-patches can have up to eight different patches for creating some very lush arrangements.

The Elevata is also upgradeable via EPROMs you can buy for a little over $100 each and install yourself. The Vocoda EPROM adds vocoder capability. Additional EPROMS are on the way and there is room for up to 3 EPROMs. With multiple (6) outputs, stereo inputs for processing external audio, and full MIDI implementation, the Elevata's at home in any studio environment. It makes an interesting alternative to other virtual analogs in its price range such as the Nord Leads and Novation SuperNovas.

Polyphony - 16 voices
Oscillators - Two with square, sawtooth, sine & formant waveforms plus pink/white/blue noise
