Roland retired Edirol in about 2010 and the PCR’s along with it. I bought a Novation controller in the same week I bought my PCR-300 way back in 2003. The ReMote25 is still going strong.
I stand corrected on the NRPN support.
Do a search on “Edirol PCR not working” and you will find the dead key issue is the most common to the point of there being PCR key repair videos on YouTube.
The actual Roland branded controller keyboard range has been the “A” range for a long time, but I’ve never used one and won’t ever buy one as I’m not convinced that they are any different to the Edirols products.
One of these days I’ll try out a CME controller, they have a reputation as great long lasting controllers with very nice action. Novation’s controllers are good but I’d like a little bit less synth action in the keys and more of a piano action.
