Description
Fire up the play-cache vst.
Synopsis
Documentation
encode_time :: RealTime.RealTime -> [Midi.ChannelMessage] Source #
Emit MIDI messages that tell play_cache to get ready to start playing at the given time.
This is encoded as Midi.Aftertouch where the key is the index*7 and the
value is the 7 bits at that index. At a 44100 sampling rate, this can
address 2^(7*4) 44100 60 = 101 minutes, which is long enough for
anything I'm likely to write. TODO since this can't represent negative
times, and the DAW likely doesn't like them either, I'll have to normalize
the output.
encode_play_config :: FilePath -> BlockId -> Set ScoreT.Instrument -> [Midi.ChannelMessage] Source #
Send the block to play, along with muted instruments, if any. Each is separated by a 0.
decode_time :: [Midi.ChannelMessage] -> Int Source #
Just to test encode_time. play_cache does this internally.
