Knob

Host to PCM-80 only. Knob values can be sent via the following SysEx. Knobs operate within the current
context of the user interface. For example, in Register mode, ADJUST is a soft knob. In Edit mode,
ADJUST varies the displayed parameter.

Note: In automation mode, the PCM-80 sends parameter values, not knob deltas.

0iii iiii Point Position (0-127). Positions should be in ascending order, and
may not be duplicated.
0000 iiii Point Value LS nibble . The point value is independent of the specific
parameter range. The point value range is from 0 [minimum] to 0xffff
[maximum]. This format allows a new patch destination to be chosen
while maintaining the contour of the patch table.
0000 iiii Point Value next nibble
0000 iiii Point Value next nibble
0000 iiii Point Value MS nibble.
000i iiii Tempo value Numerator (1-24)
000i iiii Tempo value Denominator (1-24)
