Ok First of all, I'm NOT planning on making tX an "Ableton Live on Linux". I actually want to keep the basic workflow of tX and take care of some shortcomings:
- optional Per turntable stereo-jack outputs (got that working, with my own mixer design)
- LV2 support
- OSC support
- Rubberband support (working in parts, length of slave turntables get adjusted to master turntable)
- Automatic detection of Beatpattern (don't know yet which lib to take)
- Take out the sequencing stuff (better done by some external app e.g seq24, Ardour3 via osc/midi )
- Eventual change to Qt for the Gui (as a programmer, i love Qt), but that for the far Future
So actually It should rather go along the lines of Traktor DJ (from NI) (with more than 2 turntables), than Live. I'd also like to incorporate NI idea of using a physical turntable to control tX (scratching etc.)
