Vahatraker is a MIDI sequencing companion for Linux audio setups. Adhering to UNIX philosophy, driving MIDI is the one thing it tries to do well, adhering to other doctrines.
Vahatraker 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.
This is free and open source software.
