Yeah, it does the softer end quite well. The arpegiator in the MIDI3 is pretty cool... has several different random modes that keep things interesting. And being able to adjust the mix of triangle, saw and square waves lets you dial in all kinds of nice tones. Just don't turn the resonance up too far, and you'll avoid the gnarly. I usually have mine between 1/2 and 2/3... but it's nice knowing I can crank it more if I want.
I just added my first module to my 10.1+, btw. It's the SoundMachines LS-1 Lightstrip. It was unfortunately the only module I was on the market for that my local shops had in stock when I checked on Sunday (but hopefully that'll change soon). It's fun to use as performance trigger and as a programable LFO to modulate the filter. I will say I'm a little disappointed when using it's CV for pitch... it seems a little wobbly or too sensitive or something. But even with that, I still think it's quite worth it. And I bet a quantizer would solve that pitch issue.
