A triangle core analog dual complex oscillator inspired by the Buchla 259. One of the best sounding oscillators we've ever heard, period!

Features:

30 HP width, up to 1 1/4“ in depth

All analog signal path inspired by & based upon famous west coast synthesis – a module in the tradition of harmonic generation based on additive synthesis

Internal FM bus allows for Ring Mod, AM, FM, and audio rate wavefolding, all at once!

Modulation oscillator can be slowed to LFO speed, and it's FM input is normalled to the carrier oscillator sine out for circular FM

Contains noise output and random LFO output

Multi-turn frequency knobs sweep up to 10 octaves, all pots are bolted to the panel and have no wobble to the knob!

Oscillator tuners that show when the module is tuned to an A440, and that simply always work

2 Discrete triangle core oscillators both with hard- (resettable) and soft- (inverting) syncs and selectable 1 or 1.2 v/oct tracking. Temperature compensated for tight tracking and minimal drift

Can be upgraded for thru-zero linear FM with the Strong-Zero VCO core update, Thru Zero core allows for driving the FM depth much furthrrrr than normal without the tone going sharp, as is typical with deep FM (note: swapping cores is easy but requires recalibrating the V/oct response of the oscillator)

Beautiful sounding wavefolder with a very Buchla-esque tone

Deep, metallic timbres, entirely new sphere of sounds from light whistles to weird noises

Combine with the Grand Terminal module to create a powerful 2-operator modular FM-synth
