Description
The t01 VCO from Thonk Synth is a 4HP Eurorack analogue oscillator with triangle-core. This compact VCO packs in plenty of features including LFO mode, octave switching, hard sync and linear FM.
The t01 can track up to 8 octaves and has dedicated Sine, Triangle, Saw and Squarewave outputs (10Vpp). The pulse-width of the Squarewave can be modulated via CV and there are separate coarse and fine pitch controls for easy oscillator tuning.
The VCO core is based on the super stable SSI2131 chip from Sound Semiconductor. This module is part of a new range of DIY Eurorack designed in house at Thonk HQ.
