Step Sequencer

To toggle a step in the pattern of the 16-step sequencer, use the keys:

Q W E R T Y U I
A S D F G H J K

To select one of the eight channels, use keys 1 through 8. You can mute a channel anytime using Alt + NumberKey.

Press Alt + StepKey to define microsteps (upto 3 for now).

Instrument Editor

To customize the parameters of an instrument, press the Tab key, select a field and change its value. The parameters will update automatically if the step sequencer is playing.

Left/Right: Increase/decrease value for the current field
Up/Down: Move between parameter fields

Also, you can still change channels with the numbers from the instrument editor.

To change the base note of the instrument, use the keys:

  W   E       T   Y   U
A   S   D   F   G   H   J

as in a keyboard of one octave. To change the base octave, use PageUp/PageDown.
