Been ka-noodling around with this to do an orchestral version of Ron Grainer's famous electronic theme. Right now its scored for woodwinds, brass w/ piccolo trumpet solo lines, harp and strings...do you think I should included some non-GPO electronics or electric bass/guitar or something? Or FX? Would very much be in keeping with the soul & history of the piece. My main question is this: are there any good FX (free/nonroyalty) to recommend?
