Hello, I am very new to this, so please bear with me. What I essentially need to do is record ideas of mine and store them on my computer (preferably in mp3 format) to listen to. I'll be recording max three instruments (cello, piano, something else) simultaneously. I would be doing both track by track recording and (hopefully) live recording with multiple instruments at once. This would mean I would want at least two microphone inputs for whatever I'm going to buy, right? So I can record three instruments with to mics? The better the quality, obviously, the better. But budget, portability, and ease of setup come first. My options for recording device: - 4-track Yamaha MT-100 cassette recorder. - Some good MD recorder? - My 30 dollar Sound Blaster MP3+ sound card (this would force me to do track by track recording.) Are there any other options I don't have listed? Any suggestions for MD recorders (with mic input)? Also, what's the difference between mic input and line input in MD recorders? Thanks for tolerating my intolerable ignorance!
