MIDI Patch Sources (General Purpose and Global):
Control # Function
0 - 31 Continuous controller 0 - 31
32 - 63 Switches 0 - 31
64 Last note played
65 Last note’s velocity
66 Channel aftertouch value
67 Pitch bend value
68 MIDI tempo period
69 Front panel Adjust knob
70 LFO value
71 Lowest note held
72 Highest note held
Global patch parameter numbers 70-92 correspond to microcode parame-
ter numbers 0-22. Therefore, if you want to globally patch the front panel
ADJUST knob to decay time (microcode parameter 11) you would use the
global patch parameter number of 81 (70+11). Its data value would be 69,
corresponding to the ADJUST knob control number.
The MIDI patch Offset values are generated internally by the equation:
Offset = [Source-Threshold] x Scale Factor
where Source equals the value of the specified controller.
This calculated Offset value is added to the stored (base) value of the
specified destination parameter. The sum of the offset and base values is the
number used by the audio processor and the parameter transmit routines.
The programmer should be aware that the offset values are internally
updated continuously — therefore if the programmer changes the offset
value externally it will be over-written shortly thereafter. The offset param-
eters are most useful when read to determine the MIDI patch contribution to
the parameter values transmitted by the LXP-5.
NOTE: When the LXP-5
receives
a parameter change, the received value
is used as the new base parameter value. However, when the LXP-5
transmits
a parameter value, this value equals the sum of the base
parameter value and any applicable MIDI patch offsets.
