The Keyed Mosstone is a one voice synth with a keyboard of touch pads in the shapes of three dots and four rectangles. Pressing one or some of the three circle keys with your fingers selects a note and triggers the envelope to sound the note. Top and bottom long bars are to offset the three dot keys. The left bar is envelope loop, which patches end out and trigger in of the envelope. The right bar is a sample and hold key which outputs two random voltages. The voice of the synth is a triangle wave oscillator with a noise mix, and wave folder. The envelope is a rise and fall type generator with sustain mode on or off. Inputs on the back for CV and gate, and powered by a 12v adapter.


  • The Keyboard is an array of touch pads for controlling some parts of the instrument
  • Three circles are for selecting one of eight voltages tuned by trimpots across the top of the keyboard section. These keys work in combination in a binary way to provide 8 options.
  • The top and bottom bars are offsets for the binary pitch keyboard, these can be tuned to octaves, two octaves, or whatever you want...
  • Rectangle on the left loops the function generator
  • Rectangle on the right on rising edge triggers one digital random voltage source and on falling edge triggers an alternate random voltage. holding this key also patches the end-of-function output to trigger the random voltages...
  • Two outputs for the randoms, three inputs for each key, two outputs for CV from keyboard and a trigger voltage spike

Moss Oscillator

  • The Moss oscillator is a triangle square vco with an noise source which can be sprinkled in with the oscillator before the wave folder. There is a knob control and a cv input for the amount.
  • There is a lockhart wavefolder of two transistors after the oscillator with knob and cv as well.
  • Exponential FM and linear FM inputs, the linear input having an attenuator
  • also a pure triangle and pure noise output are presented

Function Generator

  • Rise and Fall type function generator with Knobs and CV ins for both
  • There are outputs for rise gate, fall gate, end of function, and of course one output for the envelope itself
  • trigger input

Other stuff inbetween

  • VCA CV input is inbetween the envelope generator and the oscillator
  • 3.5mm Jacks across the back go power input (12v >=300ma center positive 5.5mmX2.1mm), audio output, CV IN jack, Gate IN jack
  • There is a volage inverter with an input, an output and LEDs for each
  • ground jack banana on the back
