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, so sw_lokey and 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 sw_previous is often used for legato instruments.

With sw_down / sw_up this behavior is implementation-dependent. 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.

sw_lokey and sw_hikey can be entered in either MIDI note numbers (0 to 127) or in MIDI note names (C-1 to G9)

Example

sw_lokey=48 sw_hikey=53
