If you have ever heard of Protracker or Fasttracker, then you know the drill,
if not, then you are probably too young :-)

• This tracker requires a modern browser that supports WebAudio. It's tested to work on all major browsers desktop and mobile browsers.
• Midi support is not available in Firefox or Safari.
• Minimum requirements for mobile devices: IOS9 or Android 6

Features

• Load, play, edit and save Protracker and FastTracker 2 compatible module files
• All Protracker audio effects are supported (99% accurate, in case of historical differences in playback engines, I tend to follow the Protracker 2.X one)
  • Portamento / Frequency slides (Effect 1, 2, 3, 5, E1 and E2)
  • Vibrato (effect 4, 6, and E4)
  • Tremolo (effect 7 and E7)
  • Arpeggio (effect 0)
  • Glissando (effect E3)
  • Sample offsets (effect 9)
  • Volume slides and settings (effect A, C, E10, and E11)
  • Position jumps (effect B)
  • Pattern breaks, loops and delays (effect D, E6, and E14)

• Includes the historic ST-01 and ST-02 sample disks, released in 1987 (as well as a bunch of others)

• Export to .mod, .xm, .wav, and .mp3
• Connect your Dropbox account to directly read and write your own files

The playback engine has gone through extensive compatibility testing, but as the Protracker code itself is somewhat messy and muddy throughout different versions, there's always room for improvement. If you find a module that doesn't sound the way it should, let me know! There are still some very specific Protracker 1 and 2 playback quirks that are not implemented (and probably never will as they are too bat-shit-crazy)

Missing features and bugs:

• The following FastTracker features are not fully supported yet:
  • Tremor
  • "Set envelope position" command
  • Panning Slides
  • PingPong Loops are unrolled to normal loops (There's no difference in sound but if you save your XM file, your samples will have changed.)
  • When writing XM files, patterns are not packed so the resulting files will probably be a little bigger than when saved with the real FastTracker 2.
• Safari doesn't support WebAudio StereoPanners so songs will be played in mono on Safari.
• Safari and Firefox don't support the Web Midi Api so no midi on those browsers.

How to Run
BassoonTracker is a web application that runs in your browser.
Just serve "index.html" from a webserver and you're good to go. If you want to run it locally and you don't want to fiddle with things as nodeand npm, I can recommend Spark
Download the binary for your platform, drop the Spark executable in the folder where you downloaded the BassoonTracker source files and run it.
If you then point your browser to http://localhost:8080/dev.html it should work.

How to Build

• BassoonTracker doesn't need building, the build step is optional, there are no runtime dependencies (bliss!)
• Just open dev.html in a browser to load the plain uncompressed scripts (one way to do that is by running vite or npm start on the command line)
• If you like you can build a "packaged" version:
  • I'm using "vite" for that, if you don't have it installed globally - install it with npm i
  • Use vite build (or npm run build) to build the compressed files -> index.html will be created.
  • If you make changes to the graphics, use grunt sprites to build the spritesheet. This will compact all files in the skin/src to a single .png file and will create a spritemap.

Future plans

• MIDI support -> Done!
• Undo/redo on pattern edits and sample edits -> Done!
• Implement local file system access
• Export and import of .xi instruments.
• 3SM/Screamtracker file support, maybe OctaMED too.
• Allow synth/FM instruments next to sample instruments.
• Although the tracker concept is awesome - it also would be nice to integrate it in a more modern "horizontal block compose" style interface where you can re-use and combine tracks/patterns in a composition instead of endlessly copying tracks.
• Allow multiple notes per track (or at least give the option to let them play when a new note is triggered).
• More effects (echo, reverb, flange, etc.) should probably be implemented with graphical track-envelopes instead of instrument envelopes or more numerical effect parameters. All this would require (yet another) new file format, but that seems inevitable.
• Simpler HTML/CSS-based layout - maybe the canvas approach is too heavy for really large screens? (Done, but not maintained)
• Plugins:
  • Jukebox plugins, filter on genre/rating/etc.: hit play and let it perform.
  • More expanded sample editor with audio processing features - probably as an external plugin.
  • Nibbles... we definitely need Nibbles. -> We do!
