sw_down / sw_up

Enables the region to play if the key equal to sw_up value is not depressed.

Can be entered in either MIDI note numbers (0 to 127) or in MIDI note names (C-1 to G9)

Example #


The difference between sw_down and sw_last is that sw_last is a “sticky” keyswitch - after releasing the keyswitch note, it continues to affect notes until another keyswitch is pressed. sw_down, on the other hand, is “non-sticky” and only affects notes played while the switch is held down. It could also possibly be used for true legato instead of sw_previous.

If there is a default articulation which should sound when no sw_down keys are pressed, sw_up should be defined for those regions. For example, if there is a flute with a default sustain articulation which should not sound when an ornamentation is selected using sw_down, the default sustain articulation can use sw_up so it only sounds when no ornamentation keyswitch is held down.

In ARIA, either sw_down or sw_up can be a note in the playable range, regardless of whether sw_lokey/hikey is defined or not. In rgc sfz, they can be in the playable range if sw_lokey/hikey are not defined, but if they are defined, then sw_down and sw_up notes must fall in the sw_lokey/hikey range.
