Synchronization
The MT4X has the ability to synchronize MIDI sequencers, rhythm programmers, and other devices to the
existing tracks on your tape. The following section describes some of the advanced techniques you can
employ.
When you create an overdub recording, you play along with the previously recorded tracks – matching the
tempo. This is easy for a guitarist, vocalist, or keyboard player, but not so easy for a MIDI sequencer or
rhythm machine. To synchronize MIDI instruments, you need to provide a timecode signal that the MIDI
instrument can follow. This involves recording MIDI timecode onto a track using a technique called FSK
(Frequency Shift Keying). Typically, the best time to do this is when you are laying down your basic tracks
using a MIDI sequencer or rhythm machine to set the tempo.
Some MIDI sequencers and rhythm machines are already equipped with a SYNC OUT connector. You can
plug this type of machine directly into the MT4X to record FSK onto one of the tracks.
If your MIDI sequencer or rhythm machine is not equipped with a SYNC OUT connector, you may need a
MIDI/FSK converter such as the Yamaha YMC10. You plug the MIDI/FSK converter in between your
MIDI sequencer or rhythm machine and the MT4X to record FSK onto one of the tracks.
Please refer to the user’s manual supplied with your MIDI instrument to see if it can output compatible
FSK signals.
