CHAPTER 8: APPLICATIONS
8.1 MIDI SYNC APPLICATIONS
8.1A IDM01 As MIDI Timing Master
The IDM01 can control several other slave MIDI drum machines or sequencers by turning on
MIDI Clock Out, which sends IDM01 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 IDM01. 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 IDM01 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 IDM01 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.
