Valhalla Tracker aims to be a MIDI sequencing companion for GNU/Linux audio setups. Adhering to Unix philosophy, it tries to do one thing well

  • input/output relies 100% on JACK
  • which allows for sample exact timing
  • and freewheel rendering
  • fits well between a MIDI controller and Carla/fluidsynth/Zyn
  • fast workflow with lots of keyboard shortcuts
  • allows for "unheard of" time signatures
  • starts in one second, builds in five
  • fits on a floppy

The sequencing engine is written in C, has a Python library on top of it, which can be used headless (for generative composition or whatever). The GUI is also written in Python and uses GTK through GObject Introspection.
