Methods

reset :: State set [NoteBoundary]Source

size :: set -> Int Source

toList :: set -> [((Pitch, Channel), Velocity)]Source

index :: Int -> set -> Maybe ((Pitch, Channel), Velocity)Source

change :: NoteBoundary -> State set [NoteBoundary]Source

Instances

C SerialLatch	A key is hold until `n` times further keys are pressed. The `n`-th pressed key replaces the current one.
C GroupLatch	All pressed keys are latched until a key is pressed after a pause (i.e. all keys released). For aborting the pattern you have to send a `AllNotesOff` or `AllSoundOff` message.
