"The Classic VCO is the highest quality analog oscillator module ever made. It produces the standard classic analog waveshapes -- sine, triangle, sawtooth and pulse with pulse width modulation. It also has a unique random voltage output which provides 64 random voltage levels. In the audio range, this sounds like "noise" of various colors depending on the tuning of the oscillator. In the "low" range, it can be used in the same way as a noise generator feeding a sample and hold. The Classic VCO has three exponential control inputs, one with attenuator. It also has an AC coupled linear input with attenuator and a propotional sychronization control with attenuator. In addition, this module contains a simple attack-release envelope generator (which can also be used as an envelope follower or lag processor) and a voltage controlled amplifier (VCA) with two mixing inputs. The VCA is intended to be used with the "Velocity" output of a MIDI to CV convertor but can be used as a general purpose VCA. The modulated pulse output is normalized to one VCA input while the output of the envelope generator is normalized to the VCA control input. Red and Green Bicolor LEDs monitor three of the waveform outputs and the voltage output of the envelope generator is displayed by the brightness of a fourth LED. The output level of the VCA is displayed on a four LED VU meter. The Classic VCO module contains: A five waveform pure analog oscillator An Attack-Release Envelope Generator. The envelope is set by an internal jumper for either exponential or linear envelopes. A Voltage Controlled Amplifier (VCA) A jack multiple"

Saw this one on sequencer.de.

Anyone know what that is in on the top right?

TouchBox prototype very first demo

YouTube via raidersofthelostarp.
"A tutorial showing how to create, build and upload a simple patch on the TouchBox synthesizer. The patch is really simple so the sound is very rough :).

Modded BOSS DR-110

via this auction. via Gregor

Details Google translated from German:
"Roland DR-110 inclusive. Guidance and connection diagram. Strongly modifies. Has e.g. Sync in is thus (e.g. with Döpfer MSY) synchronizable by Midi. Many additional control parameters: Bassdrum Tune and Decay (to “continuoushum”), Snaredrum Tune and Snap, HiHat filter and Decay, Cymbal filter and Decay, Noise Tune (for Hihat and Cymbal), the geilste is however the Clap with the 3 automatic controllers for pitch, Decay and phase - thus many completely new sounds are possible (see sound examples). The sound plate was transplantiert into the white large housing. Although still everything functionally as with a ungemoddeten, thus battery operation (in addition, power pack, as one wants), manual playing of the sounds with the Pads, goes everything still. The sockets right are trigger inputs, those do it however not much zuverlässug."

Roland 100m 175 Triple Vactrol Filter

via Ryk:
"The module has three separate Bandpass Filters controlled by Vactrols, based partially on the famous Korg PS3100 resonator circuit, with additional individual resonance circuits and mix section.

They are internally patched in parallel with linked audio inputs, and mod buses, to act as a traditional resonater type filter setup.
When jacks are inserted into the audio inputs and mod inputs they break the routing and the filters can be used separately with individual inputs, freq. modulation, and individual resonance controls.

The same is true of the outputs, where they are internally patched to be mixed to one output via individual level faders, or routed to separate outs, by inserting a jack in the relevant output socket."

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,
