Hey, you're on a KORG site and you ain't made a dash for a Triton yet? OK, you're not that rich yet, maybe. I'd say avoid the Trinity for its quirky touch screen behavior (done really RIGHT on the Triton, with no execution delays, etc.), although the rack module would be a great buy. I still get great mileage out of my 01/Wfd because I gathered a wad of sound disks for it early on. Cruise the links at the head of this section of SynthZone and start nabbing some of those sys-ex files. Your synth is only as good as your library.
Sure, I could use a sampler or a new Supernova II, wanna gimme one? But I get plenty of techno action from what I have.
Don't sell a synth that's 2 or 3 generations old, a mid-line Alesis FX box and a mere Mackie 1202 short. Its all in your head & hands, literally. Multitrack with ANYthing at hand and you've suddenly got TWO synths. Remember, a Juno-60 and an AkaiSs900 have made several careers in many a musty back bedroom.
