Inspired by the Event Loop, the queue is a first-in-first-out (FIFO) dispatch mechanism. Events accumulate, wait, and are consumed one at a time, each driving a state transition in the sequencer. Every jump or timbral gesture is the result of something that was previously enqueued.

Event Queue (EVQ)

Holds pending event operators to be fused into the next push. Current available ops:

Key	Op	Description
`c`	`>CHORD`	Chord event — triggers a triad.
`h`	`>HOLDN`	Hold event — sustains the note.
`r`	`>RTCHT`	Ratcheting — re-triggers the note.

Queue Operators

Spatially mapped on the keyboard. Current available ops:

Key	Op	Description
`P`	Push	Push current playhead position (or front event) onto OPQ.
`S`	Swap	Swap the top two items in OPQ.
`O`	Pop	Execute and remove the front item from OPQ.
`D`	Duplicate	Duplicate the top item in OPQ.
