Troubleshooting 101

Do I have to sacrifice one track to record timecode?

No. The MD4S generates MTC (MIDI Timecode) or MIDI Clock from the disc’s internal sync signals. So even in a synchronized MIDI system, all eight tracks are available for sound record- ing.

How many songs can I store on an MD DATA disc?

Up to 254.

Do I have to clean the MD4S heads?

No.
