next, it will play 1 repetitions of sequence 7; next, it

will play 2 repetitions of sequence 12; after that, it will

repeat steps 2 and 3 indefinitely.

Notice that the NOW field always indicates the position

within the song, not the position within each sequence.

15. To return to the Play/record screen, press the MAIN

SCREEN key.

NOTE: Occasionally you may see the "Analyzing sequence. Please wait..."

message on the lowest line of the screen, requiring you to wait briefly while

the MPC60 does some "thinking". This occurs after you make any changes in

the song, but only if the song contains a large number of different sequences.

This waiting time is normal and is necessary in order for the MPC60 to

create what programmers call an "index table" for the newly edited song.

Once this process is done, all subsequent FAST FORWARD, REWIND,

and LOCATE operations will be immediate, as well as all responses to

incoming SMPTE, SONG POSITION POINTER, or MIDI TIME CODE

sync signals.

NOTE 2: If you notice a timing irregularity in your song at the point of

transition from one sequence into another, the problem may be due to the

assignments of the PROG field (in the PLAY/RECORD screen) for the

sequence which plays immediately after the timing irregularity. 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. This problem does not apply to sequences containing only drums

tracks.
