Xynthesizr arrives and it's free (with some IAPs)

Xynthesizr = ToneMatrix + a full-fledged synthesizer + instant generative music features.
Create music easily and intuitively. Just press play, tap on the grid buttons and hear what happens. It's that simple, but that's not all.

With its synthesizer and morphing features, Xynthesizr can be a classic ToneMatrix, an arpeggiated synth, a soft ambient generator, even a drone machine, and more. Check out the built-in patterns and presets to get the idea.
