STILLSON HAMMER MARK II is a 4-track control voltage sequencer for realtime music performance. Four identical, 1v/octave calibrated CV/gate tracks directly control your collection of oscillators and percussion. Seven pages of parameters determine your musical performance, edited with a bank of 16 illuminated sliders. A series of hotkeys immediately generate or modify sequences across all four tracks, with no menu diving whatsoever. Two CV inputs and large manual controls mutate any number of sequence parameters, with programmable modulation amount per step. 32 preset slots are provided for your storage of sequencer data. The keypad, rotary encoder, CV modifiers, LED feedback (on all buttons, sliders, and numerical display) and slider bank work in harmony to allow astonishingly fast music creation across all four tracks, in an ergonomically valid user interface uncommon in modular synthesis.


  • Dedicated hot keys for instantly intitialising or randomising parameter or track data, or manipulating multiple sliders at once.
  • 4-digit numerical display provides feedback about currently edited parameter
  • Nonvolatile preset storage of 32 sequences
  • Delay, burst, and slide times track tempo changes
  • Internal clock generator or external input
  • Manual or trigger controlled start/stop/reset (reset trigger output provided)
Per track (4 tracks total):
  • 1v/oct calibrated CV output
  • Gate output
  • Mute function
  • Quantizer scale (off, 12-tone, roots and fifths, minor/major triads, sixth and sevenths, all seven modes with selectable root)
  • adjustable track length for polyrhythmic operation (all tracks follow the reset signal, and new sequences are loaded according to the length of track 1)
Parameters per step (maximum 16 steps per sequence):
  • CV value (0-8V at full scale, 0-5V, or selectable 2-octave ranges)
  • Slide/portamento (adjustable time)
  • Gate length and offset/delay
  • Burst rate and repetition count per step
All step parameters may be modulated by two external CV channels. Each CV input can be assigned to any combination of parameter pages, with the attenuation of the CV signal programmable per sequencer step. The two manual controls are large and playable and are an essential part of live performance with the Stillson Hammer.
