Have used this on both desktop and mobile and it's insanely powerful, flexible, and runs super efficiently.  A few things were slightly non-intuitive (the lfo system, the sequencer itself if you're not into trackers), but even just knowing the basics, you can patch together so many things quickly and really improvise with sound design.  I only wish it had something like Ableton's clip launcher for live performance... though you can fake it a bit by looping patterns.
