"NOTE: These series of circuit bent designs are especially made to intergrade with modular synthesizer systems. The modifications add sophisticated controls of the sound circuits of these "modular toys"
transforming them into useful modular synth extensions.
CIRC.BENT "HOMEDICS" SOOTHING MACHINE (modular synth version)
Soothing machines or alternatively "sound spa" devices are pretty much fun to mess around with their circuits since they display interesting samples of nature's sounds in 8bit resolution. I have transformed this relaxation tool to an instrument capable of producing complicated patterns with the use of a voltage controls from a modular synthesizer (tested in eurorack format).
EXTRA FEATURES
- Pitch Control Knob
- CV IN
- Audio OUT"

via the seller: "Sometimes customers can sell there boards thru The Synth Spa, like this one. But this one has something cool attached to it. A lighted bender and a 100.00 dollar coupon towards a custom color upgrade. The metal case has a bit of rust , but only a small amount, thus the reason for the custom color upgrade coupon. ( now the custom color will only cost you 150.00 with the coupon) .
This 106 received the total restoration package and it's serial number is recorded in the book of life! Where I guarantee its working ability and currently made parts for 10 years.
She a beast under the hood, I personally did the calibration and install of new electronics . The voice chips are guaranteed for life as well. The sliders have been taken apart , deoxidized , and resoldered back into the board. The power section was also rebuilt. Volume pot is smooth and clean, and the buttons are brand new tac switches. Keys have been cleaned. The internal memory now has the best of the best 106 sounds installed. Also there is a standard 3 prong power receptacle and cable that comes with this synth."

VCO2-RM
D-LFO
ADSR-VC2
DMF-2
VCA-2P
"The 2RM is equipped with seven waveforms, LFO mode, sync and waveform outputs are routed to a DC coupled ring modulator (RM). The oscillator's frequency is controlled by COARSE, TUNE knobs and FM inputs. TUNE finetunes the oscillators (± 6 semitones).
Frequency modulation (leveled FM1, FM2 and FM3 ) determinates the intensity of frequency modulation and/or pitch control. All FM inputs are carefully calibrated for 1Volt/octave sensitivity. Frequency modulation, by an audio signal, creates so called "side-bands" that consist of sum and difference of signals frequencies.
These additional frequencies do mostly have a non harmonic sound. Modulation, by low periodic waveforms, such as LFO or envelope generator creates momentary pitch shift of modulated oscillator common named vibrato (by LFO) or pitch bend (by envelope generator).
SYNC means that sync'ed oscillators frequency is tracked by the frequency of controlling oscillator;
OSC2's frequency is syncronized to OSC1's frequency. When the tuned frequency of sync-ed oscillator has the same or multiple of frequency of controlling oscillator then sync-ed oscillators waveform has no or very little "glitch" which results in a sync-ed smooth waveform (sinus waveform). The sync-ed waveforms (with additional FM modulation) are perfect for cutting edge lead sound and hard, funky basses.
PULSE WIDTH % adjusts the pulse width of the pulse wave from 5% to 95%.
WAVEFORM selects the waveform or a mix of waveforms from an oscillator. PULSE WIDTH control works also on the waveform mixes where the pulse wave is included.
Ring modulator (RM) is a classic audio effect device and due to the non harmonic character of the output signal, very useful to create metallic timbres such as bells, sweeping whistles and percussive sounds and tremolo effects (modulated by low periodic signal like a LFO). Two input signals are pre-patched to OSC1 and OSC2 outputs. Using the inputs X and Y, any other external signal can be routed directly into the ring modulator. As modulation source the ring modulator can produce a huge amount of complex waveforms both in the low and audio frequency range."
"The D-LFO consists of two identical low frequency oscillators. The LFO2 can be internally sync-ed to LFO1 by an internal switch. The TRIP POINT control the voltage point at which the waveform is sync-ed; continuously from lowest to highest point of the waveform. Additionally the external signal can be used as sync source in two modes; the SYNC T converts the external signal to a very narrow pulse for a distinct sync and the SYNC G extract pulse width of the external signal for sync with a "steady state" sync-ed waveform. The RM/AM is a ring modulator / amplitude modulator. It is coupled to both LFO's outputs and has a separate output "RM-AM" and input for external signal (pre-patched to the LFO2's output)."
