LexiconPCM 80 Version 1.10 MIDI Implementation Details
0x14 Knob Message
Host to PCM 80 only. (In SysEx Automation mode, the PCM 80 sends parameter values, not knob
messages.) Knobs operate within the current context of the user interface. For example, in Register
Banks mode, the Adjust knob is a soft knob. In Edit mode, it adjusts the displayed parameter. This
message is only useful for a remote controller.

0x15 Program Change Dump
Bidirectional. This is the method used in SysEx Automation to send Program Change messages. It may
be used in other cases, although the number of bytes is larger than a standard MIDI Program Change
message. The current MIDI Program Change mode selection (mapped, chained, off, etc) is ignored.
