0x14 Knob Message
Host to PCM 90 only. (In SysEx Automation mode, the PCM 90 sends parameter values, not knob
messages.) Knobs operate within the current context of the user interface. For example, in REG mode,
the Adjust Knob is a soft knob. In Edit mode, it adjusts the onscreen 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.
