Endorphines Ground Control


GROUND CONTROL – is the 42 hp Eurorack performance sequencer announced at Superbooth 2019. The sequencer has 4 tracks: three melodic tracks and a drum track consisting of 8 drum triggers and modulation/accent output. There are also dedicated mute buttons for each track, MIDI and USB-MIDI I/O, external CV and a 2-octave piano-style keyboard.

The keyboard serves for playing the melodies as well as entering the menus – in that method the module eliminates tedious menu diving. Each track can contain 24 patterns, which can be played separately or chained together in any order. All those tracks are organized into 24 projects. The number 24 is associated to the 24 letters of the Latin alphabet.

Ground Control features very stable internal analog and MIDI clocks preserving low jitter operation, which is crucial for tight sequencing. The patterns are entered either in 101-style step input, live recording and can be adjusted using the 303-style editor. The drum sections features a X0X-style sequencer.

Enter the menu with TEMPO>M(midi)>N and you will see the firmware number on the screen (e.g. 1.6)
