RASTER Music Tracker (short RMT) is a cross-platform tool for making Atari XL/XE music on a Windows PC. RMT uses the Atari XL/XE music routines created by Radek Štěrba from 2002 to 2009. It was a small revolution for all Atari musicians and fans.
This fork is the latest development branch of RMT, version 1.35. It is the continuation of the original version 1.28 of RMT by Štěrba and the version 1.34 of RMT by Vin Samuel.
The following versions are available for download:
- Latest daily build of 1.35 (constantly updated)
- Stable version 1.34 (2023-03-10)
- Stable version 1.28 (2009-05-19)
See the change history for the differences between the versions.
Please provide your feedback about the daily version via one of the following channels:
- Send a personal message on AtariAge or create a post in the AtariAge thread
- Send an e-mail to jac at wudsn.com
- Create an issue or a feature request on GitHub.

Note that this is as of RMT 1.28 and not accurate for 1.34 and later!
- Mono 4 tracks / stereo 8 tracks.
- 254 tracks, each with its own length (256 beats max.) and with support for track loop.
- 64 instruments (stereo, instrument table up to 32 steps - 2 types and 2 modes with loop, instrument envelope up to 32 steps with loop, portamento, filter, 16bit bass, volume slide, volume minimum, vibrato, frequency shifting, etc.).Fully automatic management of AUDCTL register (filters, 16bit basses) and/or manual AUDCTL settings.
- Support for "volume only" forced output.
- Note portamento up/down effect.
- Instrument envelope commands for note/frequency shifting and support for special "like a C64 SID chip" filtering.
- Up to 256 lines for song (with "goto line" support).
- Beat speed 1 to 255 (1/50 to 255/50 sec).
- Instrument speed from 1 to 4 per screen (up to 1/200 sec).
- Main input/output song file format: RMT song files (*.rmt).
- Input/output instrument file format: RMT instrument files (*.rti).
- Export formats: RMT stripped song file (.rmt), SAP file (.sap), XEX Atari executable MSX file (.xex), ASM simple notation source (.asm).
- Import formats: ProTracker modules (.mod), Atari XE/XL Theta Music Composer songs (.tmc)
- Support for speed/size optimizations of RMT assembler player routine for a concrete RMT module (very useful for background music in demos, games, etc.).
- MIDI IN support!
- MIDI multitimbral playing possibilities. You can use the RMT like an Atari multitimbral MIDI instrument. You have to send MIDI output from your MIDI sequencer or player to RMT MIDI input by means of some virtual MIDI cable (for example "MIDI Yoke" etc.). The MIDI implementation chart is in the midi.txt file.
Issues are tracked on the GitHub issue tracker.
There are no more changes to the 1.34 version. If you find an issue in the stable version, please test the daily 1.35 version to see if it's already fixed.
