I've been using the Roland RD-88 for a few months now, mostly in live settings, and it's pretty solid. The key action is really smooth which is distinguished for expressive playing. In terms of sound quality, it holds up well against other models in the same price range; the piano sounds are particularly realistic. I haven't run into any reliability issues either.
As for integration, it works seamlessly with my DAW and other gear via MIDI. The interface is straightforward so tweaking settings or switching sounds mid-performance is hassle-free. Definitely a good pick if you're looking for versatility and reliability!
