Description

Great value analog synth voice capable of complex FM tones, stereo filtering and more!

This 50HP bundle includes:

2x VCO (t01) kits – 4HP + 4 HP

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 Double Bubble (t08) kit – 16HP

Double Bubble is a 16HP Eurorack dual analog multi‑mode filter designed for creative sound design and flexible signal processing. Each channel features an analog filter core that can operate in one of four modes – Low‑Pass, High‑Pass, Band‑Pass, or Notch. The input of Channel A is normalled to Channel B so its easy to create stereo filter patches from a mono sound source.

Double Bubble can also be routed in serial configuration to create more complex signal paths such as a variable width bandpass or notch phasing effects. The SPACING control along with a wide range of CV inputs give deep modulation possibilities such as dynamic formant style filtering. Read more HERE

1x Triple Mod (t07) kit – 12HP

Triple Mod is a 12HP 3 channel modulation source. The default state for each channel is a an Attack / Decay envelope generator with CV control over rise and fall times, looping, linear/logarithmic slopes, trigger/gate modes and an end-of-cycle (EOC) output.

Each channel also has an unique additional mode which is accessed by pressing the loop button for 2 seconds:

• Channel A becomes a wide ranging LFO with skew function.
• Channel B transforms into a Turing Machine looping random sequencer.
• Channel C becomes a Sample & Hold (S&H) with slew options, or a slew rate limiter with separate Attack and Decay controls.

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 CAS (t04) kit – 4HP

The t04 CAS is an updated skiff friendly version of the classic Fonitronik Cascade module – a 4HP DIY Eurorack triple Attenuverter with mixed cascading output normalisation.

CAS has 3 channels of attenuvertion with bicolor LED indicators and the option to add up to 2 x gain of the original signal per channel. This allows for mixing, boosting, attenuating and/or inverting any incoming signal. The input of each channel is normalled to a +5V voltage source, allowing for each channel to be used as an offset/mactro control when the input is unpatched. 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
