I do now have all three of the pieces I mentioned - ie. TR-08, JX-03, and JP-08, along with the 25 key controller. I brought the TR-08 and JX-03 to work yesterday and broke them out on lunch break. The combo does sound great but what I think I need is a couple pedals. I got a saturation/overdrive plug on Ebay (Electro-Harmonix Hot Tubes) last night and in another month or so I might look for a decent reverb with high-pass and low-pass settings that I can link prior to the saturation.
So far my impression of the JX-03, for as simple as it is, it does have the ability to crank out some pretty warm and usable sounds. It may be a little bit before I try the JP-08 because I'm really hoping to get much more technical mastery with all of these pieces than I was with my vst synths. Even though it might sound cheesy I'm really coming to appreciate hardware again and how much you gain from having dedicated units where you can twist the knobs directly. Even a controller keyboard is a bit alienating. I know it shouldn't matter but I get that as human beings we, as well as our creativity, aren't really based fully in either the rational or practical. Either way I think this will help me keep my practice up.
If I were to throw down on more gear at this rate in the next few years, I could see myself going with more analog drum machines (like the Tanzbar) as well as the Korg Arp Odyssey or one of the Moogs or Oberheims (the later really sound gorgeous IMHO). A lot of that's in the category of course of being a bit big to take to work in a laptop bag so I'm still not sure if I'd do it but I suppose if what I have now gets me dedicated again I might consider it.
