NitroTracker is a FastTracker II style tracker for the Nintendo DS. If you didn't understand that, you might want to read up on trackers. For starters, NitroTracker is a versatile tool for creating music - everywhere. It supports the popular XM file format that is used by many PC trackers and that can be played on many PC audio players such as Winamp or XMMS.

It was ranked 1st in the NEO Spring Coding Competition 2006. In 2009, it was ranked 4th in the Top 20 Nintendo DS Homebrew.

User guide

With NitroTracker, you can carry your XMs around in your DS and compose whenever and wherever you feel like it.

Compose your melodies using an on-screen keyboard, directly edit your patterns by making selections, copying and pasting - all with the stylus. And that's not where it ends: If you don't have any samples at hand, make your own with the DS's microphone. You can even replace the samples in existing songs with your own recorded ones. There are many possibilities already and there will be even more.

The documentation with tutorials is available from the official site. You can learn how to tune your instruments and apply volume envelopes and how to hook up the DS to MIDI.
