These files might not work on the most current version of the Commander X16, or these may be held over from the previous forum. To find previous versions of the emulator, so you can test old programs, please visit Our GitHub Page

Modplayer




Plays audio files that are stored in Amiga tracker module format.




Usage





  • when running via emulator, increase the audio buffers by starting it with:

    x16emu -abufs 32


  • LOAD "MODPLAYER.PRG"


  • RUN


  • type file name, e.g. "D1.MOD" (you can change or correct it by using the "del" key)


  • press "enter"


  • enjoy!




Features





  • supports standard 4 channel mod files


  • supports mod files with size up to 504 KB or higher depending on CX16 memory configuration


  • user interface shows each channel with tone, instrument number and effect


  • mod file name can be set via keyboard




Known issues and limitations





  • sample rate is set to about 18 kHz, 8 bit, stereo to fix timing issues with channel mixer


  • volume is reduced by half to avoid clipping


  • no finetune for instruments


  • only supported effects are: "slide up/down", "set volume", "pattern break" and "set speed"


  • "set speed" effect doesn't support BPM setting


  • player speed can be slightly off as it is based on 60 Hz vsync signal wheras many mod files are based on 50 Hz PAL signal


  • first 2 letters of song name are missing due to the way how the kernal load routine is implemented


  • no control unit yet
