Personally, I disagree with Korgasm. I think the TR-Rack is very efficient. I don't understand the problem with editing with SoundDiver. It's a very simple hook up and set up procedure, it gives you all the parameters right in front of your face, and has a very decent and readable layout. Personally, I just don't do a lot of heavy programming at sessions or gigs, and don't know who would. It's impossible to take that kind of time when others are waiting. But the TR is not completely chained to software editing. You can access all of the necessary tweaks from the front panel very quickly and easily for sessions and/or gigs. Things like filter cutoff, FX editing and on/off, octave changes, levels, amp envelopes, all the things you need to make quick, on the fly edits. I've been using Korg products for almost 10 years and currently own a T3, an SGproX, a Wavestation SR, an X5DR, and my TR Rack. I've had O1's, DW's, N's, you name it, and I've probably owned it or checked it out extensively. The TR is a very powerful module that sounds second to none in the sample playback realm, but if you need the sampling and bells and whistles on the Trinity, definately go for the biggest one you can afford. The controller options are great, and the touch screen is handy, if a bit slow. My only real negative about the TR is there is no fast scrolling through parameters. This isn't a problem for selecting presets, as there are jump buttons for banks and increments of 10. But for certain parameter adjustments from the front panel, it's a little obnoxious. Other than that, thumbs up all around. Also, the one 16 part multi doesn't bother me as I only use 8 part combi's for sequencing. But if you're arsenal is limited, this may be a drawback for you.
