2. Data format

2-1. Format

We recommend the use of Standard MIDI File format 0 (where the file contains a single multi-

channel track), as opposed to format 1 (where the file contains multiple tracks).

2-2. Tempo

We recommend using tempo settings in the range of 32 - 250 bpm.

2-3. Resolution

Any resolution (such as 96 ppq or 480 ppq) may be used. For the MIDI events listed below, be

sure to allow appropriate spacing between each event (as described below) in order to ensure

correct processing by the sequencer:

• Continuous Control Change data such as Pitchbend, Expression, Volume, and

Modulation - If these messages occur in dense succession, tempo can sometimes become

unstable, so use the Thin Out (or equivalent) function on your sequencer to reduce the

data stream as much as possible. Wherever possible, leave intervals of at least 1/96

(=5/480) between these events.

• Between Bank Select MSB/LSB and Program Change - If these three events are placed

at the same time clock, the sequencer may produce unexpected results. Always leave

intervals of at least 1/96 (=5/480) between these events, and always send the Bank Select

MSB first, the Bank Select LSB second, and the Program Change last.

• Between events such as RPN/NRPN Parameter Select, Data Entry MSB/LSB, and Reset -

Always leave intervals of at least 1/96 (=5/480) between these events.

• After a System Exclusive message - Always leave an interval of at least 1/96 (=5/480).

We recommend the use of System Exclusive messages only within the setup data

(see section 2-4 below), and not within the song data itself.
