Quick Reference Grid
The grid on the control panel is a quick reference that shows the modes and what the Ctrl (control) and
Alt buttons do in each of the modes. For example, in “Play Patterns” mode, the Ctrl button is used to
select the pattern bank, and the Alt button is used to switch between playing patterns and playing
individual drums.
Tempo Knob
The Tempo knob sets the tempo of the currently playing pattern or song. The numbers around the
Tempo knob on the control panel show the beats per minute (BPM). The position of the Tempo knob is
ignored if you are using an external clock source.
Run Button
The Run button starts or stops the currently running pattern or song. The Run LED is illuminated when a
pattern/song is playing. When a pattern/song is not playing, pressing the Run button will start it at the
beginning. When a pattern/song is playing, pressing the Run button will stop it at the end of the current
pattern. The Run LED will blink to indicate that it is about to stop.
Holding hold down the Alt button while pressing the Run button changes its behavior. When a pat-
tern/song is playing, pressing Alt + Run will stop it immediately, as opposed to at the end of the pattern.
When a pattern/song is not playing, pressing Alt + Run will continue playing at the point at which it was
stopped, as opposed to at the beginning of the pattern/song.
