on_loccN / on_hiccN
Sample trigger on MIDI continuous control N. This does not involve playing any MIDI notes.
Region will play when a MIDI CC64 (sustain pedal) message with 127 value is
received. So, basically, when the sustain pedal is pressed down, this region will play.
This is useful with piano pedals - in the above example,
could be used to trigger a mechanical noise sample, whether any keys are being played
or not. It would not typically be used with hi-hat pedals, as most electronic drum kits
will send a MIDI note when the pedal hits bottom.
Practical Considerations #
on_locc/on_hicc effectively replaces the default trigger=attack. The behavior of a region which has on_locc/on_hicc and trigger=attack both explicitly specified is not defined by the SFZ specification, and that combination should be used.
In ARIA if on_locc/on_hicc and trigger=release or trigger=release_key is used, the on_locc/on_hicc opcode will be effectively disregarded, and the region will behave like a normal release or release_key region.
