A popular free program for composing music. MadTracker (as the name suggests) belongs to a group of so-called trackers - derived from Amiga's SoundTracker - easy to use programs for creating music based on instruments and sound samples recorded on different numbers of tracks. It supports all the most popular formats from other programs of this type, from MOD to S3M, XM and IT, as well as its own MT2 format.

Instruments are supported in format XI and own MTI, and samples in WAV, AIFF, IFF, OGG and own MTS. It is possible to control the program by means of the MIDI keyboard. Since version 2.5 MadTracker supports instruments and VST effects, and since 2.6 MadTracker supports ASIO.

The free version does not have the possibility to export the created songs to WAV files (OGG is available for this purpose). Full version contains several VST plug-ins, 8 built-in effects, over 70 high quality samples as well as sample songs.
