From IME:
ARGOS BLEAK is a 4-channel oscillator controller. Two calibrated control voltage inputs are quantized, processed, and sent to four different destinations. Immediate control is given for octave shift, detune, slew limit, and internal vibrato on each channel, with the semitone offset for the channel programmable as part of a preset. This module was designed to facilitate musical cooperation between oscillator designs from different manufacturers and provide a central control for multi-oscillator performance techniques difficult to execute in realtime by manipulating patch cords and tuning knobs.
ARGOS BLEAK is a quantizer that provides voltage precision over a handful of oscillators. Its main function is as the brain for quantization and tuning (coarse and fine) for up to four VCOs. Each of the four outputs has a dedicated vibrato LFO to prevent a quad LFO to be used in a patch toward something as little as vibrato. The Argos Bleak saves many settings for different configurations, even saving offsets on certain oscillators to provide chordal "presets." These presets can be clocked through by giving "chord changes". The Argos Bleak is a benevolent master control module.
Inputs The two inputs accept 0-8VDC signals to be interpreted as 1 V/octave pitch CV. Each of the four output channels can use either input or some arithmetic combination thereof. The internal quantizer is similar to the quantizer from the Stillson Hammer Mark II. Select a scale root and a scale type (or none at all), and your input CV will be processed through this and sent to the four outputs. Input channel assignments may be swapped or otherwise rearranged in response to an external gate signal.
The slew limiter may be routed before or after the quantizer. Routing it before the quantizer may lead to useful rhythmic offsets. You may select which channels influence the quantizer trigger output to fully exploit this effect in your patch. If a cable is patched into the slew gate input, the slew will not operate unless the gate is high. The internal vibrato generator has a master amplitude control for sending the modulation to all CV channels. The channels’ vibrato signals may differ in phase for thicker modulation.
Chord Processor The chord processor stores 32 presets of “chords”. A chord consists of the quantizer scale selection, the semitone offsets for each channel, slew limiter routing, and all other programmable parameters. Chords may be selected with the rotary encoder or with an external control voltage.
