Dropping or adding a full layer on a bar line is an instant, effective transition natural to live coding

A mute/cut transition simply drops or adds a whole layer on a bar line rather than crossfading or filling. It is described as instant, effective, and the bread and butter of a patched performance — a live-coding natural because muting or un-muting a voice is a single edit that lands cleanly on the next bar. In live coding this is the primary way sections connect: a breakdown is a mute, a drop is an un-mute. It requires no automation lane and is inherently reversible, which makes it the safest structural move mid-performance.

Examples

// Breakdown: comment/mute the kick layer on the bar line // Drop: un-mute it on the next bar line — instant section change

Why is muting or adding a full layer on a bar line especially natural to live coding, and how does it relate a breakdown to a drop?
