// WARNING: the tracker still writes the same song bytes. Nothing is stripped
// from a score. If a flag is 0 and a song or SFX still uses that effect,
// function, or octave, the sketch breaks: the player ignores the command and
// does not consume its parameter bytes, a removed function will not compile,
// and an excluded note is silent. That is the sketch author's responsibility.
//
// A sketch with no ATMconfig.h compiles all of these in. The 1s below match that.
// ATM.play() is always compiled. ATM_FUNC_PLAYPAUSE needs PAUSE and RESUME.
