From TidalCycles userbase
Type: ghost :: Pattern ControlMap -> Pattern ControlMap
ghost adds quieter, pitch-shifted, copies of an event after the event, emulating ghost notes that are common in drumming patterns.
d1 $ stack [ ghost $ sound "~ sn", sound "bd*2 [~ bd]" ]
The example above creates a kick snare pattern with ghost notes applied to the snare hit.
