I've been plugging my bass into my Mac's stock sound card with a $3 adapter and have been very pleased with what I've been able to capture with GarageBand. I have to wonder if a "real" input device might sound even better and something to address the latency issue might be nice. I'd also like to be able to plug up a low-z mic as well. I search and look and I see firewire input devices, I see USB II input devices, and I hear people telling me I want a sound card. Looks like a sound card might do everything that an input device does and more - but I don't understand the "compare and contrast" issues of a sound card versus an input device. What do I want? I'd love to just copy a tried-and true collection of gear (input device, monitor, etc.) that is popular and works for a Mac running Garageband with an eye to integrating that with Logic Express. Thanks for any ideas!
