I'm interested in using my laptop (1ghz cpu, 256mb ram) as a *real-time* effects processor for my electric bass. Here's my idea: Effects send on Ashdown head -> M-Audio MobilePre input -> USB 2.0 interface on laptop -> NI Reaktor input -> software programmed effects -> NI Reaktor output -> M-Audio MobilePre output -> compressor -> Effects return on Ashdown head I'm unsure about how the MobilePre's output would work, and if Reaktor will complain or not. I'm assuming the drivers for the M-Audio card would allow me to switch the output from the laptop speakers to the 1/4" output on the card. I'm not dead set on the M-Audio MobilePre; I also looked at the Audigy 2 NX. As long as I have a 1/4" input (or 1/8" input... I have that adapter) and a 1/4" output, I'm good. I don't know what the manufacturer sites are talking about with "balanced" and "unbalanced" in/outputs. I also don't have a good idea of what 16-bit/48kHz sounds like compared to 24-bit/96kHz. It doesn't need to sound perfect as I will not be using this for recording... only for live applications. Also, will latency be a problem? I don't think I'll be making absolutely HUGE synths in Reaktor, but would it be a big deal for Reaktor to, say, process an octave / distortion / reverb chain in real-time? Advice & suggestions appreciated!
