The sequencer – called sketchbook – is a matrix with fixed 8 channels and a almost endless width of steps. The sketchbook can be divided into sheets (comparable to patterns), corresponding to different parts of a song.
Every cell of that grid can be filled with a sample, parameter changes (volume, panning, pitch adjustments, playback direction, Note Off) and MIDI messages.
There are different levels to zoom in and out to make fine grained compositions or just sketch some basic 4/4 ideas. Swing can be applied to each sample individual or assigned to one of 8 swing groups. This makes the grid resolution as fine grained as the 192 steps for micro timing on an MPC.
Each sample can be chromatically pitched and defined with a probability to be played.
Parts of the sketchbook can be referenced to so called Snippets to trigger them in the play mode.
