Vahatraker is a MIDI sequencing companion for GNU/Linux audio setups. Adhering to Unix philosophy, driving MIDI is the one thing it tries to do well, adhering to other doctrines - enabling expression, with added value of:

• live editing
• fast workflow
• intuitive midi-in
• unheard of time signatures
• scenes
• fractal turtles

Frankly speaking, vht was envisaged as a re-creation of seq24 in tracker form for author's "studio needs" and offers similar functionality (and limitations). It relies 100% on JACK audio connection kit for input/output/synch and uses jack_capture for rendering. The GUI has similar dependencies as gnome-calculator and tracker paradigm was chosen to allow for rhythmic gymnastics otherwise hard to convey.

Low level stuff was done in C and wrapped in Python. Human interfacing part of contraption employs GTK through gobject introspection and was also contrived in the language we shall no longer spam about.
