I own a Roland RS-9 & absolutely love it. I live in Asia now. It's back in the US.
Over here, I'm using an RS-50 as a MIDI controller.
But there is NOTHING on the market right now like the RS-9.
It was 88 keys & under 24 pounds. If the Roland Juno series had
an 88 key synth like the RS-9, I'd buy it.
But every other 88 key synth on the market is a lot heavier.
I personally like the RS piano patch a lot. I like the organs.
I think the RS-series is under-rated. I'd buy an RS-9 in a heartbeat if I could find one.
Other synths I own are a Korg M3m, Triton Le, Roland RS50, Yamaha MU100 & MU90R.
Where I live now, I control my Yamaha modules & K1r with an M-Audio Axiom 61. It has
keys similar to the RS-9. But I don't like it. For one thing, it's just a MIDI controller - no sounds.
For another thing, the knobs aren't pre-assigned. You have to do it all yourself with software.
I control the Korg M3m with the Roland RS50 because of the knobs. The RS Series synths are
great MIDI controllers.
Out of all of them, I wish I could control the Korg with the RS-9. I just love how that keyboard feels & looks. I especially like the pre-assigned knobs.
