Furthrrrr Generator Buchla panel

Dual VCO with waveshaper

30 HP width, up to 1" in depth (super slim and therefore skiff friendly)
All analog signal path inspired by and based on famous west coast synthesis — a module within the idea of harmonic generation based on additive synthesis theory
2 discrete OTA triangle-core VCOs both with hard- (resetable) and soft- (inverting) syncs. The cores are self made custom encapsulated circuits with decent results of tracking (up to 6 octaves) as well as fine temperature stability
Selectable tracking (1 or 1.2 v/oct) by setting a jumper (we believe at last a few wigglers will appreciate that)
Bolted potentiometers, wobble free for heavy duty
Multi-turn frequency knobs sweep up to 10 octaves
Oscillator tuners that simply always work
Of course, RoHS and cat friendly
The harmonical section of the carrier oscillator involves a complex chain of waveshapers, crossfaders, wavefolder as well as the "Mood Index" with amplitude-, balanced-, frequency- and timbre-modulation.
Every parameter is voltage controlled, interacts with and depends on each others position.
The whole scheme is a bit complex for immediate understanding. We consider the better way to understand it, is to start with forgetting about the waveforms – just explore it.
