I have used a PCR-30 full-size keyboard for years in my midi mixes. Recently I have "downsized" my "studio" but this was the first one. My friend has a full-room studio littered with what he calls "analogue" equipment with wood, holes, strings etc. Not sure how he oscillates, filters or attaches his adsr envelopes to the wooden monstrosities but he claims to get good sounds as well...go figure. I will write more on my efforts to use my iPad as my main synthesizer hardware.
