Receive Channel
TONE GENERATOR
The system distinguishes between note data received via MIDI and that generated
by the internal sequencer (which includes data from the local keyboard). Hold 1,
Sustenuto, and other controllers do not make this distinction, however, and affect all
notes from both sources.
ALL SOUND OFF makes no distinction between MIDI and local data; it terminates
all sound over the relevant channel, regardless of source.
An ALL NOTES OFF message received via MIDI terminates only the MIDI-driven
notes on the relevant channel. The sequencer does not record the message.
