|Parse a MIDI Channel message.
Note that since getting the first byte is a little complex
(there are issues with running status),
the code, channel and first data byte
must be determined by the caller.
|getWithStatus :: C parser => Int -> Fallible (T parser) T||Source|
|Parse an event.
Note that in the case of a regular MIDI Event, the tag is the status,
and we read the first byte of data before we call get.
In the case of a MIDIEvent with running status,
we find out the status from the parser
(it's been nice enough to keep track of it for us),
and the tag that we've already gotten is the first byte of data.
|put :: C writer => T -> writer||Source|
|putWithStatus :: C writer => T -> T writer||Source|
|This definition should be in Message.Channel,
but this results in a cyclic import.
We do not define Controller as enumeration with many constructors,
because some controllers have multiple names and some are undefined.
It is also more efficient this way.
Thus you cannot use case for processing controller types,
but you can use Data.List.lookup instead.
maybe (putStrLn "unsupported controller") putStrLn $
lookup ctrl $
