MIDI SPECIFICATIONS

• Note 7 - Alternate Tuning

The “user tuning table” allows any key to be tuned to an arbitrary

pitch over an 8 octave range. If selected in the preset, an alternate

tuning may be achieved by modifying the tuning values from the

front panel or downloading a new table into the machine. The table

consists of 128 words, corresponding to the MIDI key range, kept in

non-volatile memory. Each word is a pitch value expressed in 1/64

semitones, offset from key number 0 (c-2). Therefore, for equal tem-

perament, each entry in the table would be equal to its key number

times 64.

• Note 8 - Program Mapping

MIDI program changes will normally correspond to internal preset

numbers 0-127. However, the user may “re-map” any MIDI program

number, assigning it to an arbitrary internal preset. This feature allows

any of the internal presets to be selected from a MIDI keyboard

controller.

See Program ➔ Preset on page 26.

PRESET DATA FORMAT

Preset data is transmitted and received using the following format: The

standard system exclusive header is followed by the preset number

(lsb, msb), a 14 bit word for each preset parameter value (lsb, msb)

starting at parameter #0 and continuing upward, a one-byte check-

sum, and the end-of-exclusive byte (F7). The checksum is the modulo

128 sum of all the parameter value bytes; that is, all of the data bytes

following the preset number and before the checksum.
