I've looked at this, and the only thing I would wish for is a separate unit that's just the synthesizer itself. It's very capable, but sticking with JUST tracker mod clips really sells the synth inside short. Even so, this is way faster than using an old-skool mod tracker on something like an Amiga.

My experience of the Tracker is that the wavetable function is fun. The granular synth is limited because you can only have one grain. Hopefully they could update that if they can squeeze more out of the processor.
