Synthrotek ADSR Eurorack Envelope Generator
The Synthrotek ADSR is a small and simple envelope generator with some very useful features. CV is additive for overall length of ADR stages in ADSR mode and add even more length to just the Release stage by adding CV into the Release jack. AR mode allows for snappy to long dynamic rhythm lengths. Very short minimum lengths, self cycling and a maximum output of 5 volts makes this tiny (4HP) envelope a very feature packed and versatile module.
- Stage Lengths:
- Attack: 4ms-2 seconds (up to ~ 4 seconds with CV)

- Sustain (based on gate length)Release 4ms-2 seconds (up to ~ 4 seconds with CV)
- ADSR Timing Sheet
- LED indication for each section
- CV over ADR
- CV over Release
- ADSR or AR mode
- Exponential or Linear Curves
- 4HP wide
Current Draw: +12: 30mA, -12: n/a, +5: n/a

MIDI TO CV EURORACK EXPANDER
The MST MIDI to CV Expander module is a tiny but extremely powerful expansion module for the MST MIDI to CV Converter
. The Expander includes an arpeggiator and allows you to have additional CV, gate, velocity, modulation and aftertouch outputs on a separate MIDI channel. You can also set it to the same MIDI channel as the Converter and use one of the three note priority selections, which will allow you to do duophony/pseudo-polyphony. You can daisy-chain Expanders together to add even more channels.
The Expander really shines when it is used with a DAW. Multiple Expanders can be set to different MIDI channels in any sequencer (like Ableton for example), making live performance with your Eurorack simple.
Recently released is our new, 1U UniBuffer module.
The 1U UniBuffer combines a buff mult and a unity gain mixer into a 1U module. It’s great for small cases where you want both functions available (like the Power Lunch).
The Buffered Multiple is a PRECISION buffered mult that is perfect for for 1V/O CV sources. The 1U Unity Gain Mixer adds input signals together and combines them for a summed output.
- Buffered Mult:
- 1 input, 4 outputs
- Precise voltage output for 1V/O sources
- Unity Gain Mixer:
- 4 inputs, 1 output
- Mixes AC signals (audio) and/or DC signals (gates, triggers, CV)
- Input signal is not boosted or cut
- Sum of inputs is the total output

Synthrotek’s blank panels do more than just fill blank space – they are a DIY wonderland.
We added small holes to make drilling and alignment easy. In 4HP and larger, the holes are spaced to fit jacks and potentiometers easily. (2HP panels use Thonkiconn jacks
only and will not fit Synthrotek’s potentiometers.)
When blank panels of any size are placed side-by-side, the geometric designs intersect. If you prefer a black panel, just flip it over, both sides are usable. Comes in 1, 2, 4, 6, 8, 10 and 12HP sizes (and 20HP coming shortly!)
