The action feels closer to a real grand piano than almost any other controller reviewers have tried. Multiple long-term owners describe the RM3 Grand wooden-key action as nearly indistinguishable from acoustic grand touch, with one comparing it directly to a $300,000 Ravenscroft Grand and finding little difference. Owners say after years of heavy daily use the keybed still feels new, and it's the reason companies like Ravenworks base their premium modified keyboards on it.

It's a dedicated piano controller, not a general-purpose MIDI keyboard. There's no mod wheel, aftertouch, pitch bend, faders, or onboard sounds, since the design purely replicates grand piano action for VST playback. Commenters note this makes it unsuitable for synth work or ultra-light key playing, but ideal for classical or jazz pianists who want expressive dynamic control through software instruments like Ravenscroft or Keyscape.

Weight and the Teflon slip-pad flaw are the biggest practical drawbacks. At roughly 30kg and requiring two people to carry, owners call it the heaviest MIDI controller around, making it essentially a stationary studio tool rather than something for gigging alone. Several also report a recurring design flaw where slip tape shifts after prolonged use, exposing sticky felt that causes keys to stick, requiring Teflon pad replacement to fix.
