"BEE GEES RHYTHM MACHINE by MATTEL 1978

Mini 20 Key SYNTHESIZER Keyboard

7-3/4" x 4-1/8" x 1 1/4"

Runs on a 9 volt battery. Has 4 buttons above the keyboard for Disco, Latin or Pop background rhythms, along with a Tempo button which adjusts the pitch or octave. It has a built-in speaker. It has a metal prop stand beneath which enables you to play it flat or at an angle...

Kraftwerk made this little unit famous by using it for a song called 'Pocket Calculator.' So it definitely has hipster cred and value for geeks of unusual toy synthesizers."

Plan B Model 13 Dual Timbral Gate Module

"The Model 13 is an enhanced derivative of the infamous Buchla 292 Low Pass Gate.

Like all Lowpass gates, at the heart of the Dual Timbral Gate is a device known as a Vactrol -- a small electro-optical coupler which opens the filter with it's characteristic ringing qualitiy. As sonically compelling as they are, Vactrols however are not perfect. While some of their anomalies are desirable (ringing for instance), others are not. Long story short - Vactrols leak. Not vactrol juice, but sound passed through them, even when you're telling them to be quiet. While it can't be eliminated without jeopardizing the ring, it can be improved upon and the Model 13 does just that, decreasing the nominal leakage associated with other LPGs by a factor of 10, from 3mv to just a under one third of a mv...barely audible even in at very high volumes.

Each gate is fitted with an offset knob which serves two functions: If no VC is applied, they act as manual level controls. Once a VC is patched they act as low threshold offsets, as the gate will not close below the level set on the pot. A three position switch selects the modes of operation: Amplitude only (no filtering), LowPass (high filtering) or Both (a combination of Amplitude and Lowpass settings). The M13 has been further enhanced by a dedicated crossfading sum output, allowing for a sonic mixtures of the information passed through both. One application for this output being when both gates are set to amplitude mode, your DTG becomes a handy 2 in, 1 out mixer!"

Peavey KOSMOS v1 Sub-Harmonic Synthesizer & HF Enhancement System

"The Kosmos provides an easy way to add depth to mixes, instruments or individual tracks without making the result sound unnatural. The KOSMOS® really can Rattle Your Planet! It is a low-frequency energy and stereo image enhancement system that will improve the audio quality of any sound system.In operation, its sub-harmonic (QUAKE) processor watches the source material, analyzes the bass, then generates additional low frequencies an octave below it. It tracks the original bass volume envelope thus avoiding the mud of other bass processors. The left-right stereo image can also be intensified with the high (XPANSE) control, which gives improved separation and clarity. All inputs and outputs are balanced. A green signal LED and a red peak indicator help you to avoid distortion. The sub-woofer output has its own 150hz crossover and level control, that is great for systems with subs."

"SSL 1450 Samplecorder module for Dotcom systems. It can record two seperate samples and then you can manipulate the pitch via control voltages! It sounds like having a small tape sampler in your modular."
