Simmons SDS-9 Analog Digital Drum Synth & EPROM Library

via this auction
"Simmons SDS-9 drum synth, soft case, 30 EPROMs in a protective EPROM case with non-conductive foam, 3 slim profile ZIFs, a CD-ROM with a digital PDF copy of the SDS-9 owner’s guide. A printed guide can be included on request but will increase the shipping charges.

The Simmons SDS9 is a 6 voice drum synth: analog bass, digital snare, digital rim-shot A/B, and three analog toms. The digital voices uses 8k or 16k EPROMs with analog filters. The drum synth can be triggered by connecting external drum pad triggers (drum pads not included) or via any external trigger input. There is also MIDI IN/OUT that has been fully tested and working (the MP3 SDS-9 recordings posted below were created with the SDS-9 and Pro Tools software).

The digital drum synth also includes is a modulation section that allows you to set the pitch and pitch bend direction. In addition to pitch and pitch bend, there are analog effects such as filters, with resonance, and a unique delay effect. The SDS-9 is a very powerful drum synth and highly recommend downloading the SDS-9 Operation Manual (link below) to read more about the functions available on this Simmons synth.

MFOS Soundlab with MIDI - Analogue Synthesizer

via this auction

"MIDI control of pitch and trigger
MIDI control of cutoff and amplitude by mod wheel
Pitch of VCO's are modified around 0 (means you can get a vibrato without the fundamental pitch moving )
It runs off and AC adaptor (included) so no batteries.
Master Octave selection switch and detune on VCO2"

MFOS Keyboard for Analogue Synths

via this auction

"A little rough around the edges and a bit battered, but it works quite well. Built from an old discarded organ keyboard and thick birch ply. Uses a PCB from Musicfromouterspace.com. Bult as a stable platform for synthesizers to sit on when being controlled by the keys. Includes 2 mini jacks to large 1/4" but I can supply 2 mini jack to mini jack instead if required."

AVRsynth virtual analogue synthesizer

via this auction

via the description:
"It is a 'Virtual analogue' hardware synthesizer based around an AVR chip which I purchased from elby designs as found here.

The rest was constructed by me onto stripboard, it has been going for years including being neglected for 1 so it is pretty rugged. Now .... I have long lost the control graphics so I had to guess which knob meant what, some are just left as mysterious! what is written on the panel should be right. Another thing is that It suffers slightly from noise from MIDI."

Infanem Effects Harmony Synth FX Pedal

via this auction
"The Harmony Synth takes your input signal and runs it through a fuzz section then two fully analog phase-locked loop based harmony synthesizers. The fuzz and harmony signals are then run through a resonant lowpass filter and a switchable amplitude tracking section. Individual level controls are available for the Fuzz, Harmony 1, and Harmony 2 signals plus a clean Instrument signal to blend your input with the synthesized voices.

The harmony synthesis circuits are (mostly) monophonic and identical to each other except for the interval selections available. The Range control adjusts the center frequency of the synthesizers and changes both the tracking range and tonal quality of the voices. It allows for them to be set to allow proper tracking, upward octave glitching, lower octave glitching, and anything in between. Faux polyphony can even be achieved by setting one voice with low Range to track low notes and another with high Range to track high notes. It's analog and not perfect but there are lots of tricks possible with just little tweaks of the Range.

Intervals available are:

Harmony 1: one octave down (-12 semitones), a perfect fifth shifted down one octave (-5 semitones), a perfect fourth (+5 semitones), a perfect fifth (+7 semitones), a major sixth (+9 semitones), and an octave up (+12 semitones)

Harmony 2: two octaves down (-24 semitones), one octave down (-12 semitones), a perfect fifth (+7 semitones), a major third shifted up one octave (+16 semitones), two octaves up (+24 semitones), and a perfect fifth shifted two octaves up (+31 semitones)

The Amplitude Tracking control allows the synthesized signals to follow the dynamics of your input signal. For stringed instruments, this means you get attack and decay that mimic the behavior of your strings. For everything, this means that the synthesized voices will follow swells, tremolo, and anything else that modulates your input amplitude.

Internal trimpots allow for adjustment of Instrument volume, Fuzz gate threshold, and a master volume control for the synthesized voices and fuzz. These can be adjusted to accommodate a great deal of input sources from the weakest guitar pickups to high-output synthesizers.

Internal voltage doubling allows for use of a standard center-negative 9VDC power supply while running internal components at 18V differential power for maximum headroom. The pedal is built with full-size Alpha potentiometers, Switchcraft jacks, Cliff bypass switch (wired for true bypass, naturally), low-noise metal film resistors, and tantalum decoupling and ceramic tone-shaping capacitors.

The Harmony Synth is an entirely new circuit developed here in Portland, OR. Everything from circuit design to PCB etching to silkscreening is done in-house for complete control over the quality of every effect."
