section 4.3.10 "Changing the velocity or duration of a group of notes after
recording".
• The PROG field:
This field permits a midi program number (1-128) to be assigned to the
active track. Each track may have a unique program number assigned to it.
To assign a program number for the active track, enter the desired number
into the PROG field. To select no program assignment for the active track,
enter a "0" in this field. Whenever a sequence is selected in the SQNC field
(before the sequence is played), the assigned program number for each track
is immediately sent out over the track's midi channel to the external
synthesizer, causing it to change to the assigned program number. This way,
all external synthesizers are immediately changed to the correct program
numbers by merely selecting the sequence.
NOTE 1: It is also possible to record midi PROGRAM CHANGE events at
any location within a track, either in real time or in STEP EDIT mode. (See
STEP EDIT for more details about this.) It is important to note that if one
of these PROGRAM CHANGE events is inserted in mid-sequence and the
portion of the sequence containing the change is played (causing the external
synthesizer to change to the new program), the original program number (as
set up in the PROG field) will not be re-sent over midi until the sequence is
reselected in the SQNC field. Simply restarting the sequence will no
implement the program change. If the MPC60 did send out all assigned
program numbers whenever PLAY START was pressed, this problem would
be corrected, but there would also be a brief delay at the start of the
sequence because the external synthesizers must take time to change their
program data. If you do want a program change to be sent out whenever
PLAY START is pressed, it is better to insert a midi PROGRAM CHANGE
event at the start of the track, using STEP EDIT.
NOTE 2: If a sequence containing these program assignments is played in
SONG MODE, the sequence's program assignments are sent out at the
moment that the sequence starts to play in the song. This can present a
problem because most synthesizers require a brief time delay while changing
programs, and this delay time will cause any notes existing at the start of the
new sequence to be delayed. This delay is brief in most synthesizers, but is
usually enough to cause a timing irregularity at the start of the sequence. To
avoid this problem, don't assign any program changes to sequences which
you are using in SONG MODE. If you need to use program changes within
the song, make sure that no notes exist at the start of the sequences
containing the program changes. Another alternative is to insert Midi
PROGRAM CHANGE events within sequences in the song at locations
where no notes exist. This same problem exists when manually changing
sequences while playing (see section 2.9.1 "Changing sequences while
playing") and can be corrected in the same way.
