Description

Main entry point for Perform.Midi. Render Deriver output down to actual midi events.

Synopsis

- state_channelize :: !ChannelizeState
- state_allot :: !AllotState
- state_perform :: !PerformState
}
initial_state :: State
data Config
config :: Patch.Config -> Config
addrs_config :: [(Patch.Addr, Maybe.Maybe Patch.Voices)] -> Config
perform :: State -> Configs -> Events -> (MidiEvents, State)
type MidiEvents = [LEvent.LEvent Midi.WriteMessage]

default_velocity :: MSignal.Y Source #

This winds up being 100, which is loud but not too loud and distinctive-looking.

data State Source #

Performance state. This is a snapshot of the state of the various functions in the performance pipeline. You should be able to resume performance at any point given a RealTime and a State.

I don't do that anymore, and this is left over from when I cached the performance. I removed the cache but left the state visible.

perform :: State -> Configs -> Events -> (MidiEvents, State) Source #

Render instrument tracks down to midi messages, sorted in timestamp order. This should be non-strict on the event list, so that it can start producing MIDI output as soon as it starts processing Events.
