I would love to say this sound module is great! But I haven't even had the chance to use it because I'm still waiting for my order that I haven't even received yet after weeks and weeks of waiting.

Bought for live performance instead of using my phone. It works exactly as described, runs my garage keys usb keyboard and makes the full general midi sound set. The piano is OK and some if the synth sounds are good, but the overall sound quality is not great, and there's a quiet distorted version of the sound mixed in at low levels which makes it unsuitable for performing with at low volumes.

The overall sound is like an entry level Yamaha pwm keyboard from the mid nineties. The windows 95 default dls sound file is similar, maybe slightly better.

It has one other fatal flaw, which is it cancels an existing note if you play it again. It's a jarring effect on sounds with a slow decay like strings. Because of that, even though it has 64 not polyphony, it often feels like it has much less, those notes go missing

The buttons and controller wheel work fine, there is a tangible click when the wheel moves round, but it usually ignores the very first click. Easy enough to adjust to.

Tl;dr - interface simple, battery good, easy to use, latency low, but sound is poor. Use for practising, not performing.

I was a little sceptical about this box, given the price but the sounds are pretty good with a very respectable Grand Piano patch. Headphone level is also very good. Build quality is excellent too. I bought it to enable me to practice whilst I am away from home using my Korg Taktile controller keyboard powered by an connected to the host-in port of this little box. For a mobile battery-powered solution, there isn't much else out there to compete if you have a controller keyboard that needs power over usb and does midi only over usb.
