Hi all, I'm getting ready to start playing shows with a band that will mix live instrumentation with material from a laptop (primarily using Live, and ChucK at some point I hope). I've never done this before and I'm not sure of the best way to connect a laptop to a typical rock club's mixer/PA. I've found a small number of answers on the web that range from a simple cable between the laptop's headphone jack and RCA inputs on the mixer, to a firewire audio interface and a stereo DI box. Audio quality and hum from AC power are mentioned as reasons to go with more advanced solutions. I don't want to spend money and carry around these devices unnecessarily, but I'd also hate to be unprepared or inflict bad sound on the audience. There must be a lot of experience with this on this list, so what do you think? Apologies for the arguably off-topic post, but I wasn't sure where else to turn. I'll try to redeem myself with something more directly ChucK-related in the future. Thanks, -Jay
