so since i last posted in this thread i've been on a gear buying frenzy, obviously not necessarily following @Leviathant 's original mantra of i do not need this. the damage so far:
korg kr55 (so early depeche mode it hurts- used one of these on a frank just frank track last year and love it)
yamaha rx5 (individual outs- thank god)
waldorf blofeld desktop synth (will use kawai k4 as midi controller as well as on its own. i bought this primarily to get the samples of an rs09, which costs almost as much as this and can only do the one thing, so this was mostly a logical buy that should open some more synth possibilities without chucking $ away at more space-eating synths)
and i even got the ol' 606 modded with individual outputs by a friend who's good with things like this. i also have my eyes on a roland r8 mkII, so that's probably next when i get a few bucks. somebody help me.
