I want to start Computer-Based recording at home, but I have a few questions. I've seen tons of websites like http://www.shopjt3.com/introductory_MIDI.html that tell you what you basically need to get started. However, they fail to mention what the items are used for or why you need them. I don't have enough experience yet to know exactly what everything is used for. Like I said, I'm new to this. Anyway, a few basic questions: 1)Are you supposed to have a MIDI Interface (to record synth) and an Audio Interface (to record vocals, MIC instruments, etc)? And those hook right up to a PC with USB right? 2)Do you need a Preamp and an Audio Interface? I don't get the difference, they look the same. I found some AudioInterface/Preamps from M-Audio, but they only have 2 MIC Inputs. 3)What are PCI Interfaces for? Are they just a substitute for Audio Interface? 4) With my midi interface, there is a delay between when I hit a key on my keyboard and when the sound comes from my speakers. Is this because of my computer or the interface? These questions probably sound dumb to you guys, but I need help. Thank you.
