I only need (want) an interface between my bass and the USB port of my Windows Vista laptop for a very limited set of purposes: 1. playing back my sound when I am practicing 2. recording a very few pieces for my own benefit and enjoyment, maybe including the addition of a basic keyboard and/or drum track. Two possibilities are the Line6 POD Studio GX and the M-Audio Fast Track USB, both of which cost about the same (~ $99 usd), have effects plug-ins, and include Ableton Live Lite software. In other words, they seem to be very similar ON PAPER. I've read most of the reviews and threads on the two, but can't decide between them (or some other choice, perhaps). Does anyone have any experience with either/both unit and have any opinions?
