Korgasm...
I agree with you, there is nothing better than a wood old black piano in the middle of a living room
But my wife has different opinion as our new home is a small one and in my small studio room the space is limited.
Triton is excellent (as you know) for everything but classic sounds. Its pianos, even with the extra PCM card i own, are useless. When i sold some old gear i bought the Yamaha S80 as a master kbd to drive my rack modules. I found that it has some of the best pads,EP,vintage and ,using PLG boards, excellent analog voices and grand pianos. It has very good Rhodes and 60s,70s organs. Though it has a two line LCD its editing is very easy. It is not Triton on insertion FX routing but has its own quality and sound signature. I like it a lot.
I think that Yamaha didn'd realize that they built their best synth. It's not THE workstation but has the sound,build quality,keyboard feel,synth engine,polyphony etc. i ever wished for.
As you understand from my setup, i prefer keyboard synths instead of racks. This happens because many times i use just a single one of them for studio recording. So i want to have my favorite sounds and kbd feel with me. As i was in market search for a good 72 or 88 keys synth i saw a Roland XV-88 prerelease demo and i played a little with it. It really has THE sounds and THE keyboard (if you like weighted action).
The sounds are JD990,XV/JV and many new ones. The overall sound quality is better than those synths as XV series synth engine has new AD converters and true stereo samples for most of the tones. The FXs are brilliant and the number of them enough for most of realtime playing or studio recording.
The only thing i didn't try is the piano PCM board but hearing a CD sample i found that Kurzweill has now a competitor.
XV has nothing to do with prior Roland keyboards. It has better sound, clean output, better FX, and a keyboard that in my opinion has better feel than Roland's Axx master kbds.
I'm sure that soon Roland will introduce workstations (aka SEQ,large LCD etc) based on XVxxxx.
So if you need to know: Triton - S80 or XVxx the answer is simple for my and my needs:
Triton for dance parts and atmospheric pad tracks.
S80 for EP,analog (with plg150/AN board),vintage organ tracks.
Roland XV for pianos,drums and classical tracks.
... and
K2600 for sampling anything else
That's only my personal opinion and just for my needs and setup.
PS: I write and play soundtracks, R&B and slow rock.
