Adds (or removes) attributes from notes.

Uses control modification, this is a control or pitch call that can modify controls other than the control track in appears in.

This call returns a VCFunction.

This call is a curve intorpolator, intended for the curve argument for calls that interpolate curves.

Adds or transforms note in a style idiomatic to a particular instrument.

Inverting call.

Can emit lilypond.

Depends on the next event.

Adds ornaments an existing note, generally to its attack.

Transforms Score.Events.

Depends on the previous event.

Call uses randomness, and depends on the random seed.

This call emits events with the args set, and requires a postproc call to emit the proper events.

Takes sub-events.

This transformer runs under inversion, via under_invert.

Saves an argument in event_delayed_args, which means it applies an Attribute, and relies on a postproc to complete the transformation.

This is the other half of a delayed call. It expects an entry in event_delayed_args.

Give this call Derive.PrioBlock when imported. This is a special hack just for the block call.
