Notes: 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. Thereis 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).
Current draw: V+ max 10mA, V- max 8mA
Notes: The MST Expressor allows you to use expression pedals with your modular, taking a "hands-off" approach to expand your control and creativity. It has two identical powered expression pedal processing units in one handy module, allowing you to do things such as:
Control volume with your foot
Attenuate CV or audio if no expression pedal is plugged in
Add positive or negative voltage with the flick of an ankle:
Sweep a filter cutoff
Direct audio volume control
Attenuate and expand external CV
LFO rate adjustment
Modulation amount control
Current draw: 28mA on +12V; 28mA on -12V
Module depth: 24mm
Notes: 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.
The Expander connects to the MIDI to CV Converter using an I2C cable (included).
Notes: 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
Notes: The MST '07 Buffered Multiple is the original buffered mult design invented by George Mattson in 2007. It's a precision mult that is perfect for 1V/O CV sources. A signal plugged into Input 1 will be available from all 14 outputs. Break the chain by adding a second signal into input 2; signal 1 comes out 4 outputs and signal 2 is available at the remaining 10. Plug in as many as 4 inputs, each split 3 or 4 times. What you put in, you get out.
Current draw: V+ max 42mA, V- max 42mA
Notes: The MST Unity Gain Mixer adds input signals together and combines them for a summed output. For example, if you put in a 1V source and a 3V source, the output will be 4V. It's mainly used for CV, but it can also be used to combine audio signals together.
A unity gain mixer is handy in several ways:
Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
Re-shaping two CV sources with a single envelope.
Combining different wave shapes or LFOs to make crazy sounds.
Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.
Notes: 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.

Notes: 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.
Compatible with the following hardware:
Windows XP, 7, 8, 10
Mac OS X (any version)
Linux (tested on Ubuntu 14.04)
iPad & iPhone with a MIDI adapter (like an iRig MIDI)
Android devices (3.1 or later) with a USB OTG cable and USB A to B cable (like a USB printer cable)
Notes: 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 ipoppierî 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.
Notes: The MST Noise/ Sample & Hold / Track & Hold Module supplies you with all the noise and random goodness you need in one small 4HP package. White, pink, and slow-random noise are just a patch away. The white noise is normalled to the signal input or input your signal of choice and break the normalled connection. To activate either the S&H or T&H, just supply the module with your clock source to start generating stepped random control voltages.
Notes: The MST Ribbon module brings control to a whole new surface and fills out an already generous selection of modules designed by George Mattson. The Ribbon module pairs with Synthrotek's Ribbon Controller Touch Interface modules that are available in various lengths in both 3U and 1U formats. Control Voltage, Gate and Pulse outputs allow for mega control over pitch, modulation, quantization, volume and more! Also connect your external signal into the EXT SIG IN jack to bypass the modules on-board voltage for passive external attenuation.
