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.

It can load the following module formats: 669, AMS, AMF, DBM, CBA, DIGI, DSM, FAR, GMC, GDM, IMF, IT, MOD, MDL, MTM, MXM, OKT, PLM, PSM, PTM, S3M, STM, ULT, UNI, and X.

Export is possible into the formats: XM, MOD, and WAV.

Supported sample and instrument formats: WAV, IFF/XI, PAT

MilkyTracker’s key features:

• Fasttracker II like, custom graphical user interface with context menus
• Supported on multiple platforms including portable devices
• Very accurate .XM replay compared to FT2
• ProTracker 2/3 playback modes for playing and editing .MOD files
• Various resampler options including emulated Amiga 500/1200 sound output
• Choose between a modern and a true-to-FT2 editing scheme / keyboard layout
• Tabbed user interface for opening and playing up to 32 modules simultaneously and for exchanging data between them
• Over 30 imported module formats
• Basic archive support for loading zipped, powerpacked and UMX modules directly
• Rendering songs/patterns to disk (.WAV) or directly to sample
• Powerful sample editor featuring waveform generators
• In-depth instrument editor featuring envelope zooming and scaling and support for copying and swapping instruments and samples across tabs
• Low latency audio driver support
• MIDI In support
• Module optimizer
• Internal file browser option
• Various font sizes for improved visibility of pattern data
• Prospective pattern view option
• Playing and editing simultaneously
• Live mode for seamless pattern changes

A couple of facts:

• MilkyTracker is not based on any common module replay. Its core MilkyPlay has been in development since the mid-90s, originally as a Digitrakker .MDL player.
• MilkyTracker development started a decade later for the Pocket PC and it still fully operates on rather humble PDAs.
• MilkyTracker is and will stay a 2nd generation tracker. There are already several good 3rd generation trackers out there.
