RMT is a cross platform tracker for the Atari XE/XL pokey (Pot Keyboard Integrated Circuit) chip. It can create songs in either 4 channel mono or 8 channel "dual pokey" mode.


The developer of RMT, Radek "Raster" Štěrba, died in a tragic accident in July 2011. A very special thank you to Raster for creating such a helpful tool, every tune made with it exists because of you.

Capabilities



RMT's main features are:

  • 4-channel mono or 8-channel stereo mode

  • Frame editor: can support up to 256 lines, with 254 different tracks

  • Instrument editor that can support up to 64 instruments. Includes settings for vibrato, volume slide and filter. Has an envelope table for volume, distortion, filter and portamento/pitch changing. Has a separate table for arpeggios/ornaments.

  • Can import .mod and Theta Music Composer .tmc files. Exports to .sap, .xex and .asm. You can also save instruments (.rti)

  • Allows separate speeds for instruments and song.

  • Midi support

  • 8-channel mode allows for stereo SAP's to be produced (4 left panning channels, and 4 right). Note that for major battles, 8-channel SAP's are forbidden from the SAP category, due to stereo SAP being a hacked feature only exclusive to RMT. Instead, BotBr's should use either the Wild Card category, or if available, the SAPx2 category.

    Quick set up




    Raster Music Tracker can be downloaded from here
    .

    In order to get sound from RMT, the .dll files (apokeysnd.dll or sa_pokey.dll,
    sa_c6502.dll) are also required. RMT will still be usable, but with no sound output. In order to save modules in RMT, a "Go to line xx" command must be used in the module (via the frame editor).

    On Linux, for running RMT with Wine, you might need to type those commands for getting some specific dll: "winetricks msvcirt" & "winetricks mfc42".
    Still on Linux, if you have a problem with the "step" option (default set to 1) which will increase to 2, 3, 4 etc every time you enter a note (then adding extra random unwanted spaces), then just select the "0" step, then hit the "alt" key, it should lock the step option. If it doesn't stay, try "alt+1" for example.

    Composing
    When you open RMT, it will default to a stereo (double pokey, sap (format)) project. You will need to create a new project for a standard, four channel pokey file. Click on the top right pattern list (song edit) to add new patterns. Patterns are global, and you can remove a pattern by pressing backspace over it while highlighted. Pressing delete will delete the whole row.

    Use the keyboard, or midi functionality(!), to enter note data in your patterns. RMT does not start you off with a default instrument that produces sound. For the beginner, it is best to load one of the instruments included with your files as the instrument editor can be complicated and confusing. Pressing space bar will scrub a complete note and move down a tick, while backspace will not remove the volume data.

    RMT will not allow you to save without a "go to pattern" loop in the song edit field. Press G while in this field to add it where you wish, and it can be deleted and moved just as easy as any other pattern.

    Expert Tricks




    *The instrument effect (vibrato and pitch shift) in the instrument editor will not function if you do not set a delay value. This means that a value of "01" will be immediate, while "00" will be OFF.

    *When in stereo pokey mode, instruments will posses stereo volume parameters. By mirroring a pattern on both the left and right channels, and with different volume envelope settings on your instrument for right and left, you can create a simple panning effect. Of course, you can get much more creative with your pan sweeps than that.

    *Be wary that certain special frequency settings for your instruments will effect the whole chip. This means some of your other instruments may stop functioning correctly.
