Live-Tune Targets

The 29 parameters a MIDI knob, pad or web-console control can move while a show is running. Each names the target of a param action in [[midi_control.cc_map]]: the holder that heads its section, a dot, and the parameter. A knob sweeps a scalar or bucket-selects a choice; a pad steps a choice on.

Mapping One#

[[midi_control.cc_map]]
type = "cc"              # cc | note | pc
number = 13              # the controller number
action = "param"
target = "effect.decay"  # a heading and a row below

A target is only live while something that declares it is on screen — the Declared by column is that list. A knob on a target the running scene does not declare moves nothing, silently.

mode#

The display mode's color pipeline. A row's target is mode. and its name.
