subsequence.constants.instruments.gm_cc

General MIDI Continuous Controller (CC) constants.

Standard MIDI CC assignments (0-127). These are supported by virtually all GM-compatible instruments, synthesizers, and DAWs.

Two ways to use this module:

1. As constants - reference CC numbers directly when sending MIDI CC messages:

   import subsequence.constants.instruments.gm_cc as gm_cc
   
   @composition.pattern(...)
   def sweep (p):
           p.cc(gm_cc.FILTER_CUTOFF, 127)
   

2. As a cc_name_map - pass GM_CC_MAP to the cc_name_map parameter of @composition.pattern() and use human-readable names like "filter_cutoff" or "sustain_pedal" in your CC calls:

   import subsequence.constants.instruments.gm_cc as gm_cc
   
   @composition.pattern(channel=1, beats=4, cc_name_map=gm_cc.GM_CC_MAP)
   def synth (p):
           p.cc("filter_cutoff", 100)
           p.cc_ramp("expression", 0, 127, shape="ease_in")
