How Sequences are Organized
A sequence can be thought of as a segment of multitrack tape of
variable length. Depending on the sequence contents, it could be a
two-bar repeating drum pattern, an eight-bar verse, or an entire
200-bar multitrack composition with time signature and tempo
changes. The MPC3000 holds 99 sequences in memory at one time.
Normally, only one sequence can play at one time, unless the Simul
Sequence feature is on, which allows two sequences, or one sequence
and one song, to play simultaneously.
Within each of the 99 sequences are 99 tracks that contain the
actual MIDI events. These can be thought of as the tracks on a
multitrack tape recorder—they each contain a specific instrument or
piece of the total arrangement, but they all play simultaneously. For
example, track 1 could be drums, track 2 percussion, track 3 bass
guitar, track 4 piano, track 5 horns, track 6 more horns, etc. Each
track can be assigned as a Drum track or a MIDI track, but not
both. MIDI tracks contain normal MIDI data recorded from the
MIDI input and played out through the MIDI output. Drum tracks
are the same as MIDI tracks except for the following:
1. The output of the track plays to the internal drum sound
generator.
2. You can record drum notes into the track using the front
panel pads.
3. In sequence editing screens, note events in drum tracks
are visually identified and selected not by note number
only as in MIDI tracks, but also by the pad number and
sound name currently assigned to the displayed note
number.
4. Drum tracks are not affected by the Transpose function.
In order for the sequencer to play external synthesizers, it must
send its notes out through MIDI on one of the 64 output MIDI
channels (16 channels for each of the 4 MIDI output jacks). On the
MPC3000, each track can be independently assigned to output its
notes through any one or two of these 64 output MIDI channels.
Ticks and Bar.Beat.Tick fields
The timing resolution of the sequencer is 96 divisions per quarter
note (96 ppq). Each one of these divisions is called a tick.
In many of the sequence editing screens it is necessary to enter the
start and end of the region to be edited. This is done using a three-
part field, called a bar.beat.tick field, containing a bar number,
