I am a 31 year old doctor and relativly new midi hobiest. I use at this point an MC505 which I love, however can't find a memory card for and the bitch is full. I also have a CS1X, Prophet 500 and several low end drum machines. I love electronica, however I am not now or ever aspiring to be a pro. The doctor thing keeps me buisy enough. I could definately use some help with the basics.
