• 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 mem-
ory. Each word is a pitch value expressed in 1/64 semitones, offset from
key number 0 (c-2). Therefore, for equal temperament, 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 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 checksum, 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.
