-Understanding the Effects Rack
-------------------------------
-
-All audio track types (Input, Output, Group, Wave, Synth, and Aux) have
- an effects rack into which audio plugins can be inserted in a chain.
-Currently each rack can accomodate up to four plugins.
-
-MusE currently supports LADSPA plugins and DSSI effects plugins.
-
-One must carefully consider how many audio inputs and outputs a plugin has,
- and how may channels the particular audio track has (1 mono or 2 stereo),
- and how MusE uses the plugins in the rack.
-
-MusE will try to internally create as many independent copies (instances) of
- a plugin as necessary, to satisfy the number of channels in the audio track.
-Basically it divides the number of track channels by the number of
- plugin audio inputs or outputs to determine how many copies to make.
-First it examines the number of plugin audio outputs, and if there are none,
- it will examine the number of audio inputs, and if there are none,
- it will simply use just one plugin copy.
-
-For mono tracks with plugins having more than one audio input or output,
- MusE uses the first input or output and ignores the rest.
-
-For stereo tracks:
-
- Plugin Plugin Independent Real number Real number
- audio audio plugin of track of track
- inputs: outputs: copies: input route output route
- channels used: channels used:
- -------------------------------------------------------------------
- 0 0 1 0 0
- 0 1 2 0 2
- 0 >= 2 1 0 2
- 1 0 2 2 0
- 1 1 2 2 2
- 1 >= 2 1 1 L only! 2
- >= 2 0 1 2 0
- >= 2 1 2 2 2
- >= 2 >= 2 1 2 2
-
-Notice that on a stereo track with a plugin having one audio input and two
- audio outputs, only the first track input route channel is used (left only).
-
-These same rules apply to inter-plugin audio when more than one plugin
- is in the rack chain. Extra audio outputs of one plugin may be ignored
- by the next plugin if not used.
-
-Currently plugins with no audio outputs are not really useful in MusE,
- chiefly because plugin control outputs are not used or displayed.
-Nor are specialized plugins with many inputs and/or outputs.
-
-Nor are so-called 'realtime' control plugins which use audio inputs
- and outputs for control signals.
-<<<
- Loud noise alert! Beware of using such plugins in an audio effects rack.
->>>
-
-
-Example: Consider a stereo Audio Input track with these effect rack
- LADSPA plugins:
-
- comb_splitter Comb Splitter by Steve Harris, and
- tap_stereo_echo Tap Stereo Echo by Tom Szilagyi
-
-The Comb Splitter has one audio input and two audio outputs.
-The Stereo Echo has two audio inputs and two audio outputs.
-
-The stereo Audio Input track will therefore ignore its second
- input route connection. It will process the left input only,
- separating it into stereo with the Comb Splitter, passing the
- split stereo signal into the Stereo Echo, finally producing
- stereo output available at the Audio Input track's output routes.
-
-
-One improvement would be not creating unused redundant plugin copies
- between plugins in stereo tracks.
-For example, for a plugin having one audio input and one audio output,
- feeding a plugin having one audio input and two audio outputs,
- the extra copy of the first plugin is redundant and not required,
- but currently it is created anyway.
