#super_sticky ⇒ Object Also known as: ss

toggles super_sticky mode, a mode where any explicit values used to create MIDI messages automatically become sticky – whereas normally the explicit value would only be used for the current message.

e.g.

note “C4”, :channel => 5

will have the exact same effect as

channel 5 note “C4”

while in super sticky mode
