I'm thinking of purchasing either MicroKorg or SL MkII 25 late next month. I've already got a couple of good keyboards with a nice feel, so i'm not overlay worried about what the keys are like. But I was wondering what I would get the most out of. i've got a couple of soft synths that i could use in place of the MicroKorg and i don't yet have a MIDI controller or a control surface (excluding an iPad with TouchOSC. But I hate touch screens for stuff like that!!) I feel like i could really use a controller, but at the same time, i'm yearning for a hardware synth. what should i get?!?!
