Parameters 7

NameTypeRangeBehavior
Hold/LenbuttonIn step-entry mode, adds a hold step (extends last note). Hold + Octave changes pattern length in steps of 8. Hold + Note key sets non-8 pattern length. Hold + Rest toggles muting of the current mode output.786
ModebuttonCycles through Sequencer, Quantiser, and Triggers modes. The associated LED indicates which mode is currently active.786
Note Keysbutton8 white mechanical note keys used for step entry, transpose, pattern page navigation, saving/loading patterns, and trigger step toggling in pattern mode. Black keys set clock divider.786
Octave/PattbuttonSets octave offset of keyboard during step entry. During playback with Play held, changes tempo. With Hold held, changes pattern length in steps of 8. Also navigates pages in pattern mode.786
PlaybuttonToggles playback of all sequence modes. Also used in combination with other buttons for tempo change, pattern load, and transpose toggle.786
Rest/DivbuttonIn step-entry mode, adds a rest step. Hold Rest + black note key changes clock divider. Hold + Rest toggles muting of the current mode output.786
StorebuttonInitiates step input when pressed (clears current sequence). Press again to end input. During playback activates overdub mode. Hold + note key saves pattern to bank.786
