Chapter 10: Syncing to Tape and Other Devices

3. MIDI TIME CODE:

MIDI Time Code is similar to SMPTE timecode except that the

timing information is converted into a signal that is sent over

MIDI. As such, it cannot be recorded on tape.

4. FSK24:

This is the general-purpose tape sync code commonly used by

inexpensive drum machines and sequencers. FSK24 stands for

Frequency Shift Keying at 24 2400Hz/1200Hz transitions per 1/4-

note. This code contains no location information, so when syncing

to it, you must start both devices from the beginning of the song

in order for them to play in sync. Because of this, the MPC3000

always plays from bar 1 when FSK24 sync is received. This code

does contain tempo information, so the MPC3000’s tempo set-

tings are not used when syncing to FSK. Also, FSK24 signal is

always generated from the SYNC OUT jack when the MPC3000

plays.

5. 1/4 NOTE CLICKS:

In the event that no sync signal exists on tape, this feature

allows the MPC3000 to sync to any percussive sound playing 1/4-

notes.

The Mode field in the upper left corner allows the selection of one of

these five sync input sources. The fields in the Sync In section vary

according to the sync mode selected.

If MIDI CLOCK is selected in the Mode field, the following screen

is displayed:

===== Sync In ====== ==== Sync Out ====

Mode:MIDI CLOCK MIDI sync:OUT A

Shift early (ms):20

MIDI Input:2

Song pointer:ON

==================== ==================

<SyncIn=OFF> <GenSMPTE>

In this case, the fields are:

• The Shift early field:

This field is used to compensate for any sync delays or

delays that are produced by slow synthesizer attacks. It

does this by shifting the MPC3000’s playback earlier in

relation to the sync signal by up to 20 milliseconds. If the

sync playback appears to be late, adjust this field until

playback is exactly on time.

• The MIDI Input field:

This field is used to select which of the two MIDI inputs,

input 1 or input 2, will be used to receive the MIDI sync

signal. It is often desirable to devote one MIDI input to

1 2 ... 202 203 204 205 206 207 208 209 210 211 212 ... 275 276
