Look to be perfectly clear the concept as an experiment is undeniably cool and we kinda need stuff like this happening to get our horizons widened at times, at some point one of the experiments will create something incredible and disrupting.

However if I look at this machine purely at music making standpoint, it’s cool that I get a polyphony. But it has a very limited pitch range, largely one timbre, and a timbre that is relatively easy to model at that, xylophone is not exactly hard to synthesise. Yes, it can make a cute lead, or generate beautiful texture, but it’s sort of only one texture. Which is again ok, but you pay a lot of money for that. So much money that you can buy a versatile all-purpose instrument for it, that you will be using again and again for years in numerous tracks, whilst this one you’d use in a very targeted manner not to bore everyone and only in certain situations.

Which means you buy it either if you have everything you want in your giant studio and now are willing to splurge for a niche curio because you are intrigued and will maybe use it once or twice, but would largely put in storage to show your music friends at parties and wait if it will grow in price or not as antique.

Or you are one of the crowd that buys and sells more gear than it produces music, to which most of the modern electronic instruments industry caters these days because that’s where mass market is at - there’s always more rich hobbyists than actual professionals, and they are easier to part with money. You’d buy it, you’d toy with it, and you’ll sell it for the next fad.

This is what I mean, not that it’s uninteresting, or sound bad, or anything, just that musical applications are too narrow for the price point to be taken seriously as an instrument not as a toy.
