MST Mono Voice

MST Mono Voice System


“If you’re looking to take the jump into modular synthesis or even looking to add a new voice to your existing setup then Synthrotek has put together a package worth checking out. This MST Mono Voice System is a complete modular synthesizer in a small, portable, powerful package.

It comes with everything you need for a full voice, including the oscillator, envelope, amp, midi/cv input, filter, lfo, mult, and output. Of course since it’s modular, you can still experiment and change components out in the future. Put it next to your current setup, use it as a jumpstart into modular syntheses, or make it your designated travel synth since it already comes with the travel friendly Power Lunch case!”


Housed in Synthrotek’s Power Lunch, the MST Mono Voice System is a powerful analog monophonic FULLY modular synthesizer. Includes a power brick and a 20-pack of patch cables.

Modules Included:

MST MIDI to CV Converter

The MST MIDI to CV Converter is a translator between digital devices and analog synths, allowing you to connect your modular system to a keyboard, computer, phone or tablet.


MST Voltage Controlled Low Frequency Oscillator is another tiny, useful module packed to the gills with features.  Manual and CV control over rate with 3 discrete waveform outputs.  A square wave can be used to clock modules such as our Noise, Sample & Hold module. Great for creating vibrato, tremolo or other classic modulation techniques.  Great for frequency modulation, especially when connected to the MST analog VCO.


The MST VCO is a 100% analog 6-octave 1V/O trackable precision oscillator with full pulse width and modulation controls and with 5 waveform outputs.

MST Dual Envelope

The MST Dual Envelope is a simple-to-use yet complex dual envelope generator.  Channels 1 and 2 are both normalled to each other to cycle when the other respective channel hits end of cycle, allowing for really interesting ping-pong effects.  Each channel also has an end-of-cycle trigger output with LED indicator.  Thereís a normal and inverted envelope out.  The inverted envelope out can be further modified by the +5 offset switch, which allows the inverted waveform to travel in the positive.  The + output level allows the envelope signal to go between zero and the maximum voltage rail.  Attenuate the output level down for a more subtle envelope (adjust to taste).

MST Low Pass Filter

The MST Low Pass Filter is a precision analog dual slope output 2 & 4 pole filter. Simultaneous -12 DB and -24 DB outputs with CV control over all parameters. Can be used as a 1V/O sine wave oscillator


The MST Dual 2164 VCA is a precision AC (audio) & DC (gate triggers or control voltage) Voltage Controlled Amplifier in 6HP.  Each channel has a linear or exponential response switch, the exponential resulting in a ìpoppierî response.  Adjustable output level and bleed if you want to mix in your unaffected source audio.  Butters your toast all the way to the edge.

1U UniBuffer
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.

1U Stereo Output Mixer
The 1U Stereo Mixer is intended for pannable stereo output, but it is also suitable for both DC (Gates, Triggers and Control Voltage) & AC (audio) signals. It has 2 channels with 2 inputs per channel

Any hardware that I personally stock will be sent out the same or next business day and should arrive within 3 to 5 business days.  Some products ship directly from the manufacturer or the manufacturer’s warehouse and should arrive in most locations within 5 to 7 business days. Special order eurorack systems, cases, and some modules are built to order by the manufacturer and will arrive within 5 to 14 business days depending on the item.

In every situation I will keep you updated through the entire process and I am always available for questions should any arise.
