Impulse Tracker

Impulse Tracker (インパルストラッカー) is a multi-channel sound tracker created by Jeffery Lim. It is the last MS-DOS based tracker. The tracker was based on the Driller Engine 2000 arcade board, supporting up to five FM and SSG channels, as well as the same two PCM channels. Later versions supported the Driller Engine 3000 and other arcade boards.

Many Drillimation games nowadays use this format for music, and the most recent games have channels that skyrocket to 32 or more channels.
