resume normal operation. Now the set MIDI channel will be stored in the device
memory.
START/STOP button
This button starts or stops the sequence playback. Sends START/STOP messages
to MIDI OUT.
Step selection button 8/16
The 8/16 LED indicator is not lit - only 1st 8 steps are selected for programming.
The 8/16 LED indicator is lit - all 16 steps (1-16) are selected.
Step selection button 9-16
The 9-16 LED is not lit - first 8 steps are selected for programming.
The LED 9-16 is lit –9-16 steps are available for programming.
8 buttons STEPS
Pressing one of the step buttons switches the state of this step to trigger note
on/off.
SOUND SELECTION button
This button selects one of the RITMOBOX’s drum sections for editing on the
sequencer. Short pressing on the button allows to choose a specific sound for
programming on the steps.
TAP mode

MIDI IN
MIDI notes are transmitted in real time to 5 trigger outputs in the following order:
CH-48 note, OH-50, G1-52, G2-53, G3-55.
If MIDI CLOCK messages are received, the sequencer will synchronize with MIDI
CLOCK and will disconnect its internal clock. When synchronized to MIDI CLOCK,
the tempo control can be used to select the amount of MIDI CLOCK per step (1-
16). When the MIDI CLOCK message are not received within 1 second, the
sequencer switches back to its internal clock.
The MIDI START message starts the sequencer.
The MIDI STOP message stops the sequencer.
The MIDI CONTINUE message starts the sequencer from the last step.
MIDI OUT
MIDI CLOCK messages are sent from the MIDI OUT. MIDI notes in messages are
sent via MIDI OUT for MIDI control of other external midi devices.
