• 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.
