120 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.
Section 5: Song mode 121 Converting a song into a long sequence: While song mode is very useful for quickly creating a song format, it can be very cumbersome for detailed editing, because of the constant switching back to sequence mode, the necessity of copying sequences, and the necessity of remembering which sequence plays at which step. For detailed editing, it is much easier to record your song into one long sequence instead of using song mode, but song mode is very useful for quickly assembling the basic arrangement of a song. The MPC60 has a feature which allows a song to be automatically converted into one long sequence. This feature actually copies all sequences in each step end-onto-end into one long sequence. This allows you to quickly construct a song using song mode, then convert it to a sequence for detailed editing using the much more versatile sequence editing features. This feature is accessed by pressing the EDIT key and selecting option 8: CONVERT SONG. This is described in detail within the "Editing sequences" section of this manual.
