SetPattern

Give one of a sequencer track’s eight pattern slots new contents, and with it the UI’s current word on the track-level settings that ride on a block — see PatternBlock.

The block travels by value. It is Copy and about two and a half kilobytes, so receiving one is a memcpy into memory that already exists: no Vec to free, no Box to drop, nothing for the audio thread to hand back to the allocator. The first pattern a track is given allocates its player, exactly as SetInstrument allocates a voice array; every one after it does not.

Fields

track_id: usize

slot: u8
