sw_lokey / sw_hikey
Defines the range of the keyboard to be used as trigger selectors for the sw_last opcode.
Basically, this tells the SFZ player where the keyswitches are.
As such, it's normally going to be the same for the entire instrument,
sw_hikey will be set under the ‹global› header.
This affects sw_last keyswitches. On the other hand, sw_previous keyswitches
can be outside of this range - and indeed often must be, as
is often used for legato instruments.
With sw_down / sw_up this behavior is implementation-dependent.
In ARIA, either
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_up notes must fall in the
sw_hikey can be entered in either MIDI note numbers (0 to 127)
or in MIDI note names (C-1 to G9)
