Exciting new HTML 5 Chip Tracker appeared

September 21, 2010 · Posted in Uncategorized 

The recent builds of firefox have included support for realtime synthesis through javascript, and I though I would get in on the fun and build a toy with them. I of course went overboard, and decided to make something that you could actually use to write music with, and implemented a tracker. To note, this is a prototype, and rather than discarding it without showing it to world, I have posted it here for people to play with, and potentially dissect.

The tracker currently allows for 8 channels of monophonic patterns, and each channel controls a synth that has either sine or noise waves, with a simple AD volume envelope.

The worlds worst help file follows:

  • arrow keys navigate
  • enter goes down one screen, escape back up one screen
  • the bottom two rows of keys are used for entering notes, like a piano keyboard
  • places that seem to take numbers, try typing numbers into them, it should work
  • not everything that is on screen is actually implemented
  • spacebar stops and starts the song
  • / goes down one octave, ’ goes up one octave
