Fostex X-28 - Tape Sync

Example 3: Tape Sync
Tape sync is the process of using one of the tracks on
the X-28 to synchronize operation with a MIDI se¬
quencer, which in turn is used to control several in¬
struments simultaneously. A MIDI sequencer is basi¬
cally a multitrack performance recorder, that allows
you to record and play back MIDI-compatible instru¬
ments. Using tape sync with a MIDI sequencer offers
many advantages:
• MIDI-controlled instruments need not be recorded
on tape, thus freeing up track space for acoustic
instruments and vocals.
• Better overall sound quality is achieved when the
MIDI-controlled instruments are mixed directly to
the master recorder during mixdown.
• Greater production flexibility is achieved through
tape sync since you can change the MIDI-recorded
musical parts and even the sounds (with the ex¬
ception of tempo) right up until the final mix.
Note: Since MIDI signals cannot be recorded directly
onto tape, an FSK-to-MIDI converter is required.
This device converts the MIDI clock data from
the MIDI sequencer into an FSK (Frequency
Shift Keying) signal, which is then recorded to
tape. In playback, the FSK signal is converted
back into MIDI data for synchronization with the
sequencer. Most modem sequencers, rhythm
machines and MIDI control devices have these
FSK circuits built-in: in some cases you may
need to purchase an external converter.
