Pros: - Small. - Light. - Affordable. - Easy to connect to a computer and update. - Can be run on USB battery power or included wall adapter. - Keyboard affords unique playing capabilities that let you modulate what you're playing both with the hand on the keyboard and the hand on the knobs. - Matrix interface is super intuitive. If you want to change how your sound works, you just can. Need to drive the cutoff threshold with the LFO? Just go there on the matrix and say how much you want the one to impact the other. Easy. - Lots of interesting arpeggiation and sequencing features, which are all fairly well-documented by the manual. Cons: - Limited effects. There's no bitcrush, reverb, delay, overdrive, etc., pretty much just a filter. You'll have to output to something else if you want to spice things up. - Tutorials tend to be either "here's what I did" or "here are the keys you can press" and not "watch as I navigate the soundspace to create my desired voice." Overall, I think it's hard to find something this fun and usable at this price point. I'd recommend this even if you were trying to introduce a younger user to semi-modular synths.
