What is an A2I file?

An .A2I file is an Adlib Tracker II Instrument file.

A2I is a file extension unique to Adlib Tracker II. A2 was an innovative music-tracking program in the 90s, loved by demoscene and chiptune artists for its small size and low system requirements. By exploiting the creativity offered by such a program, musicians could make beautiful music.

Adlib Tracker II uses instruments, patterns and sequences of notes to compose music. Using patterns and instruments together, you can make music in different styles.
