MilkyTracker is an open source, multi-platform music application for creating .MOD and .XM module files. It attempts to recreate the module replay and user experience of the popular DOS program Fasttracker II, with special playback modes available for improved Amiga ProTracker 2/3 compatibility.
Renoise is a contemporary digital audio workstation (DAW) based upon the heritage and development of tracker software. Its primary use is the composition of music using sound samples, soft synths, and effects plug-ins. It is also able to interface with MIDI equipment. The main difference between Renoise and other music software is the characteristic vertical timeline sequencer used by tracking software.
Schism Tracker is a free reimplementation of Impulse Tracker, a program used to create high quality music without the requirements of specialized, expensive equipment, and with a unique "finger feel" that is difficult to replicate in part. The player is based on a highly modified version of the Modplug engine, with a number of bugfixes and changes to improve IT playback.
16-bits FastTracker is a clone of the infamous DOS tracker but made for modern computers with a GPU and CPU and monitors with 60Hz refresh rate.
This is a crossplatform C64 music editor. Supports output via Dag Lem's reSID engine, the HardSID 4U USB device & HardSID soundcards or CatWeasel MK3. From V2.0 onwards the editor includes more powerful step-programming (wave/arpeggio, pulse and filter), 63 instruments, more instrument parameters & pattern commands. May be less userfriendly than V1.xx, but you can import V1.xx songs and instruments to see how the corresponding V2 features work.
ChibiTracker is not currently in development but downloads are still available from Freecode (http://freecode.com/projects/chibitracker ) & SourceForge (https://sourceforge.net/projects/chibitracker.berlios ). ChibiTracker is a portable IT (Impulse Tracker) clone. It is not a 100% clone though, as it adds more features, such as chorus and reverb, stereo samples, an advanced sample editor and more. The user interface also presents some changes, as it can be custom themed and resized.
