Documentation

data Patch Source #

The Patch is derived from a Patch.Patch and contains all the data necessary to render a Event to a midi message. Each Event has an attached Patch.

Patch

Fields

patch_name :: !ScoreT.Instrument
The name for the instrument as used in the score. It should globally identify the instrument within this score.
patch_keyswitches :: ![Patch.Keyswitch]
Keyswitches required by this instrument. At higher levels, a single instrument can respond to a variety of keyswitches, but at the perform level, each instrument of each note is specialized to the particular keyswitches intended. So this is normally empty, but filled in by convert prior to perform.
patch_hold_keyswitches :: !Bool
If true, the keysitch has to be held while the note is playing. Otherwise, it will just be tapped before the note starts.
patch_control_map :: !Control.ControlMap
Map control names to a control number. Some controls are shared by all midi instruments, but some instruments have special controls.
patch_pitch_bend_range :: !Control.PbRange
patch_decay :: !(Maybe RealTime)
Time from NoteOff to inaudible, in seconds. This can be used to figure out how long to generate control messages, or possibly determine overlap for channel allocation, though I use LRU so it shouldn't matter.

patch_from_settings :: ScoreT.Instrument -> Patch.Settings -> Patch.Patch -> Patch Source #

default_decay :: RealTime Source #

Somewhat conservative default decay which should suit most instruments. decay will probably only rarely be explicitly set.
