To connect a sustain pedal, see “Using a Sustain Pedal” on Page 31. CONNECTING POWER You can power your MD-1600 from either: • internal batteries (see “Using Batteries”) • standard AC power using an optional AC adapter (see “Using AC Power” on Page 8) Notes: Cautions: • Use only fresh batteries of the required size and recommended type.

42-4043.fm Page 46 Tuesday, August 3, 1999 6:51 AM NOTES ABOUT THE MIDI IMPLEMENTATION CHART The “MIDI Implementation Chart” on Page 58 illustrates the details of the MD1600’s MIDI function. An O in the chart means that the MD-1600 has this feature; X means it does not have this feature. This section explains what the MD1600 can do. Basic Channel — MIDI uses up to 16 channels to exchange data. As in a TV broadcast, different channels send different data.
42-4043.fm Page 47 Tuesday, August 3, 1999 6:51 AM All Notes Off — This feature is a kind of panic button: it stops the sounds currently playing. The MD-1600 only receives this message. Active Sensing — This means the MD1600’s sound turns off in the event the connection cable to MIDI IN terminal is accidentally disconnected.
