8.1 MIDI SYNC APPLICATIONS
8.1A SR-16 As MIDI Timing Master
The SR-16 can control several other slave MIDI drum machines or sequencers by turning on
MIDI Clock Out, which sends SR-16 timing information down the MIDI line.
1. Turn on MIDI Clock Out (section 6.6).
2. Program the slave units to not follow their internal clocks, but to accept external MIDI Clock
and Start/Stop data. Refer to each device's manual to find out how to do this. Enable the
slave's Song Position Pointer if it is available (or it may be available all the time and not need
to be specifically enabled, as is the case with the Alesis HR-16 and MMT-8).
3. Press PLAY on the SR-16. The slave units should start at the same time, and progress at
the same tempo. If the slaves respond to Song Position Pointer, you can start an SR-16 Song
at any point, and after a few seconds the slaves will catch up and synchronize from that point
on.
The following diagram shows an SR-16 serving as the MIDI system master clock, with an HR-
16 drum machine and MMT-8 sequencer set as slaves. Note that both devices must be set to
accept external MIDI clock messages.

8.1B SR-16 as MIDI Timing Slave
The SR-16 can slave to a MIDI master clock source by turning on Clock In. Example: This lets
you slave the SR-16 to a MIDI sequencer on which you have recorded other instruments.
1. Set the SR-16 Clock In to on (Section 6.5).
2. Make sure the master is set to generate MIDI timing data (refer to the unit's manual for
specific instructions on how to do this). Enable Song Position Pointer if necessary.
