Firstly, Welcome to the synthzone nylon oxygen!

Hi Ed

Nylon oxygen, you need a synth? We know this disease here. All us here have contracted it to some degree. Ed knows very well when it comes to keyboards. He has contracted nearly every varient strain of the disease LOL.
I have had my run with it as well, but not to his mastery. His advice can save you greif, anguish, and a lot of money too.

That was quite a list.
Among it, I noticed the Waldorf Q listed.

I have a Waldorf Q (the big one). I don't know if it meets his budget, heh, there is no doubt whatsoever of it meeting the need. Not a speaker made on the globe that it cannot bring to its knees by the way. Kraut power! hehe (I can say that 'cause I'm German, or well, my mom is.) It may not be quite as versatile as an Andromeda A6 sporting 9 LFO's but the sound quality and richness can even bulldoze that and in fact the patch on my Kurz that took me several months to perfect in its programming. I have heard no keyboard less than the size of a 75 square foot wall with a more rich and powerful sound than big Q.

Analog phat w/o a fat budget? Well, how about the predecessor to the JX8P?

A virtual analog. The Roland JP8000.

It's not expensive. Maybe a little more than the usual hobbiest - but there's no one "usual" that comes to this site. I would say that the sound of the instrument would meet the need unless you've left the Milky Way.

Lastly, Get a computer.
