"Pitch sources:
* 2 independent VCOs
* Made entirely of vacuum and gas-filled tubes
* Range >2 octaves using CV, octave switching allows range from 33 Hz (low C) to more than 2 kHz.
* 3 waveforms: thyratron sawtooth, square, and square with suboctave
* VCO2 may free-run or be soft-synced to VCO 1
* Numerous patch points allow enormous flexibility

Waveshaper:
* Unique circuit with soft clipper and pulse adder (shapes waveforms from VCOs by adding small pulses to top of waveform at discontinuity)
* Made entirely of vacuum tubes
* Settings: disable, soft-clip only, and soft-clip with pulses added to signal. Latter circuit allows simulation of noise source.

Filter:
* Unique multimode circuit allows it to be used as a lowpass, treble/midrange bandpass or bass bandpass filter.
* Continuously variable control allows mixing of filter forms in any proportion.
* Made entirely of vacuum tubes.
* Range of treble resonance switchable, 400-1700 Hz. Bass resonance tunes from ~100-350 Hz

VCA:
* Unique circuit using a pentode tube
* Made entirely of a vacuum tube
* May be modulated with the AR generator only, or with the control voltage generated on modulation bus 2

Modulation:
* 2 envelope generators, A(S)R and AD, both triggered with input gate signal. Both may be combined on either modulation bus to create ADSR.
* 2 independent LFOs, triangle waveform, range <0.3 Hz to more than 5 Hz.
* 2 modulation buses allow combining the A(S)R, AD, and two LFOs as needed to affect any CV input in the audio circuit (VCO pitch, VCO squarer waveshape, waveshaper pulser, filter tuning).

Main CV input controls pitch of both VCOs (Hz/V response).
Gate input triggers envelope generators, accepts 0-5v or 0-10v gate voltage.
6AL7 "eye" tube displays status of LFOs and A(S)R control voltages on three separate glowing green bar graphs.

Miniature joystick performs multiple jobs: vertical motion affects pitch of both VCOs, horizontal motion affects tuning of filter.
Press joystick in to trigger envelopes.

Features
Size: 6U high standard EIA rack mount, 3" depth below rack panel. 11 vacuum/gas tubes. Weight about 20 pounds with AC adapter. Draws 12 volts (AC ONLY) at 3 amps."

"The forthcoming v1.1 of Expert Sleepers Silent Way has an enhanced OSC implementation that makes it possible to use with the popular TouchOSC iPhone app. This video shows this in action."

shiner hex oscillator + light box in photo feedback loop

YouTube via danielfiction
"here we have two wooden box circuits interacting with each other. the hex oscillator is made in the style of nic collins: six photocells mixed to diodes and competing for voltage dominance. it's housed in a 9.99 gram weight box with a sliding lid so user can control how much light is getting in. let it all hang out.

the light box is an original circuit made with a solid state relay. it pumps out AC in beat frequencies between an audio input and 60 hz. so the lights flicker in response to what you plug into it. in this case, the hex oscillator is the input, which in turn is modulated by the flickering light, and ta daaa! a light-based feedback loop.

autofocus can't handle the intense flickering, so go on and get blurry!"

Doepfer Drums Analog Modular

YouTube via Analogger
"Doepfer / Livewire modules
I just stuck a bunch of patch cables together to see what would happen. The bass drum sound came from the A105 24db lowpass filter (very fat)

Osillators and noise was used as perccussion sounds and were processed thu the Livewire 105 ssm VFC - I used the hp ouput - very gnarley sounding"
Some KORG KAOSS Pad in there as well.
