"this is a diy project to build a sequencer for my modular synth using an arduino mega as a controller. it is an ongoing project and is intended as an educational experience, not a commercial project. the original concept was a sequencer i designed in reaktor based on an ernst haeckel drawing. it is essentially a 12 step sequencer with each step (I -XII) representing a note in the chromatic scale. The controls allow the user to play phrases within a selected scale and constrained to a certain number of notes, beats and measures. At the same time, a user can alternate between two notes using a 4 bit binary counter."

in this video i am controlling a synthesizers.com/diy modular. there are two pitch outputs and two gate outputs used."

"This is the Ruin Electronics CDS-0 (Compact Drone Synth). This is a one of a kind instrument. It was professionally built and designed by Ruin. The unit is housed in a sturdy aluminum case.
The CDS-0 is a 100% Analog synthesizer. The CDS-0 was a prototype that never went any further, but is still a remarkable and inspiring unit.
This device was used by Ruin on several recordings and during some live performances.
The CDS-0 has two Voltage Controlled Oscillators with Triangle and Square wave shapes. The oscillators have Tune, Modulation Amount and Volume controls. There is a Low Frequency Oscillator for modulations with Triangle and Square wave shapes. The LFO has a Rate control and a switch to select Triangle, Off or Square. There is a Noise source with a frequency control and an amount control which is summed with the LFO for modulation and sent to the audio path as well. The frequency control is controls the speed of a sample and hold from normal white noise to bit crushed arcade sounds to sub audio clicks. There is a Ring Mod that takes osc 1 and modulates it with osc 2, the Ring Mod has a level control. The noise source also has a mix level for the audio. Finally there is a gain control and final level control to the output.
Drones, buzzes, sweeps, chirps, noise sweeps, arcade blasts, ring mod, clangs, clanks, are sounds that can be made with this device.
The units approximate measurements are:
7.25" width x 5" depth x 3" height
The unit features:
2x Square/Triangle waveform VCOs (Voltage Controlled Oscillators) with individual tuning per oscillator, modulation amount, mix, and waveform switch.
Triangle/Square waveform LFO (Low Frequency Oscillator) for modulation. The LFO has a speed control and a switch to select Square/Off/Triangle.
Noise Source The noise source has a frequency control, frequency range switch, a level control for the audio mix, and an amount knob which sums the noise with the LFO for modulations.
Ring Mod by default the ring mod takes osc 1 and modulates it with osc 2, but an audio signal can inserted into the 1/8" jack on the back to override osc 1 as the carrier of osc 2. The Ring Mod ha a level control.
CV input for VCO control you can use the CV input to sequence the CDS-0 with external gear.
Output Overdrive The output stage is capable of nice gritty distortion with its own gain control.
1/8" Output
12v DC adapter power input."
"This is one of only 50 black SidStation Ninja's made. It is in perfect condition and has only been used in my smoke free home studio. I am the one and only owner of this SidStation Ninja. It makes amazing sounds and has brought me hours of joy. I am liquidating my studio and am very sad to see this one go, it was the prize of my studio. It has sat idle for the last 3-4 years. Powered on and tested as of 11/20/12. This is an opportunity to own a unique piece of synth history. Included is the original box (one corner was chewed on by my cat), the original manual, and the original power supply. It is updated to the most recent OS."
"Here we have a Moog MG-1 Synthesizer. This one is in excellent cosmetic and functional condition. It has had several modifications done to really harness the full power of this great synth!
1. 1/4" output jack with hotter output than the stock RCA jacks (Jack under "Output to Amplifier L")
2. 1/4" input jack to run external audio through that moog 24db filter! (Jack under "Output to Amplifier R")
3. The top switch on the left side panel is a 3-position toggle to switch between 3 different LFO speed ranges, slow, fast, and stock.
4. The bottom switch disables the LFO to OSC 1, enabling sweet sync and ring modulation effects!
5. The Knob controls the pulse width of OSC1 square wave, giving you more timbre control"
