The first is a collaborative uber-project studio built with my oldest friend Will that boasts over 300 pieces of musical electronics. My second studio is a much smaller affair in my home. It is comparatively modest with about 20 instruments and a few effect pedals.
Not surprisingly the idea behind the big studio is to have the broadest sonic palette at our fingertips. The sonic arsenal here is vast and exciting. It took 15 years to build and, I have to admit, it is as much a gear-pig's wet dream as it is a place to make music. It ranges in vintage from the Clavioline through the Monotron and offers keyboards, drum machines, effects pedals, wind controllers, stringed instruments. Analog and digital mix in a completely organic fashion and we can (and have) connected pretty much everything together to see what would come out.
My "small" studio has only one underlying philosophy - fly under the objections of my wife. I make liberal use of a laptop and a one-or-two-instruments-at-a-time approach.
What is interesting (to me at least) is that I don't feel limited when working at home. I'm quite confident that I could spend the rest of life exploring the few items there without ever seeing the edge of my creative universe.
Also of note is how frequently I find myself gravitating to the same instruments in the big studio that I have at home. In two respects this isn't too surprising - familiarity breeds confidence and efficiency. These are barely acceptable alternatives to refined music talent (which I lack). They are also factors that maximize productivity in limited time.
So I wonder, does it make more sense to get to know a few instruments deeply, or to be able to change on a whim to any tool your fancy?
