Description

Note: the Triple Mod is not included in this bundle but the above video gives a good demonstration of the T01 VCOs

Dual VCOs with a range of waveforms and frequency modulation

This 18HP bundle includes:

2x VCO (t01) kits – 4HP + 4HP

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. Read more HERE

1x Dual VCA (t03) kit – 6HP

The t03 VCA from Thonk Synth is a 6HP Eurorack dual voltage controlled amplifier module. This compact VCA has some clever signal normalisation allowing for it to be used as CV macro controller and expandable VC mixer as well.

Each channel has a button for switching between linear and exponential response curves. Linear is typically best suited for CV/modulation signals while exponential is better suited for audio signals. Read more HERE

1x DOA (t02) kit – 4HP

The t02 DOA is a dual 4HP DIY Eurorack attenuverter & offset module. Scale, invert and offset your control and audio voltages to dial in precise modulation. The DOA features two identical channels with bipolar LEDs to indicate the polarity and amplitude.

The input signal travels first through the attenuverter stage, then the offset is added, so changing the offset will not affect the attenuversion. Both inputs are normalled to +5V, so that when nothing is patched in, the bigger knobs works as an offset between -5V & +5V. If the output of channel A is left unpatched then the signal is mixed into channel B. Read more HERE
