Detailed Description

Turns a flat event list into per-part controller timelines and a note list.

The engine has no MIDI output, so nothing can be read back from it: every piece of channel state has to be tracked here.

Function Documentation

build()

Sequence ts::sequence_builder::build ( std::span< const MidiEvent > events )

nodiscard

Builds a sequence from a flat event list, ordered by position.

channel_from_block()

int ts::sequence_builder::channel_from_block ( int block )

nodiscardconstexprnoexcept

Converts a GS block number to a MIDI channel.

The block number is not the channel: block 0 is channel 9 (the drum part), blocks 1–9 are channels 0–8, and blocks 10–15 map straight through.
