	future sound systems gristleizer filter tg3 the gristleizer filter presents one of the key components of the gristleizer in a eurorack module - its jfet-controlled multi-feedback band-pass filter. its characteristics are not unlike a wah-wah pedal, whilst also being able to create other vocal tonalities, especially with several summed in parallel. whilst originally controlled by the gristleizer's oscillator, the tg3 can be controlled by any control source available in a eurorack system. as well as a couple of frequency control inputs, the tg3 also adds register and resonance controls to the original filter circuit. the register control shifts the resonant frequency of the filter core itself, whereas the frequency control affects the gating of the filter's jfet. the resonance control allows the circuit to self-oscillate easily, allowing for the tg3 to be used as a sound source as well as a filter. the tg3 also incorporates a drive parameter (with final clipping circuitry added for taming the filter core) as well as an output level control. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $170.00

	make noise rené rené is deep, but all you really need to know: patch one clock to x-clk, and a second clock to y-clk, adjust clock rates and/ or divisors, tune voltages per location (the knobs) as desired. adjusting those two clocks relative to each other will create seemingly infinite variations on the theme that is your sequence. much joy may be had without any further knowledge, but make boise is certain you will want to know more, so read on. rené is the world's first and only cartesian sequencer for music synthesizers. named for the french philosopher and mathematician rené descartes, it uses his cartesian coordinate system to unlock the analog step sequencer from the shackles of linearity. like the classic analog sequencers, there are only 16 steps on rené, each having an associated knob with which the note for that step is tuned. however, using rené the patterns are not limited to 16 steps in length because the path taken through those steps is, for all practical purposes, infinite. in fact, rene does not "step" at all, but rather it maps coordinates to locations in a grid, and because if this, it is possible to move in ways that you would never imagine a step sequencer to move. for this reason, we call the 16 steps on rené "locations," and rather than one clock input there are two; one each for the x-axis, and the y-axis. the primary goal of this sequencer is to have a maximum amount of artist controlled musical variation, with a minimum amount of data input. there are no menus, all editing is done real-time, and thus, the programming of rené becomes a key performance element. the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $400.00

	wmd phase displacement oscillator mk1 this hybrid vco has all the feel of an analog vco but with the benefits of digital waveshaping. the pdo will easily find a home in your system! the pdo exists to utilize the phenomenon of phase modulation (pm). this allows for the relative phase difference of its outputs to be set or modulated, producing very interesting sounds. the result is similar to frequency modulation (fm) but affects the output to a greater degree without affecting the stability of the initial frequency. pm has the same benefits of quadrature filters/sine wave generators and greatly exceeds their capabilities at audio rate modulations. pm is highly useful for for creating metallic and bell tones and very controlled harmonic interactions. because pm affects the relative phase and not the frequency of the waveform generated, the pdo can self modulate its pm inputs. thils creates complex harmonic signals that seem to vary in frequency but are quite stable. phase modulation is also quite powerful when using the pdo as an lfo. adjusting the relative phase of each output allows for very precise modulation of other modules. each output can have any of the available waveforms simultaniously. there is a myriad of modulation possible with the pdo! the unit is in good physical condition and works perfectly. for more information, please click here. our used price : $340.00
