Daisy and Bela are great for low-latency interactive audio :)

But I think Arduino is a good choice for this.

1. The microcontroller isn't generating audio onboard, it's driving solenoids to hit something. Arduino can do that — the solenoids have travel time but Bela wouldn't solve that.

2. This is more like a sequence playback machine, there's no continuous real-time interactivity. Play/pause is the main interaction and a few ms is ok.

(If you wanted to duet with it latency-free the top of the xylophone is completely exposed so you can just play it normally.)
