All numbers are represented with hexadecimal (00-FF.)

Resources are limited and all share numbers. Chain 0x00-FE is the same on any channel and phrase 0x00-FE is the same on any chain.

Supposedly chains/phrases stop at 0xFE and not 0xFF.

Notes in a phrase with an instrument of "--" change pitch without retriggering envelope.

Blank chains or phrases are not played. To insert spacers you must use an empty chain or phrase which is typically named 0x00 or 0xFE.

Blank chains or phrases are rendered with a dimmed color to make it easier to tell they are blank.
