Hi. This is my first post. I hope you can help me out. I really havent got a clue about digital converters or sound cards. I'm using a Yamaha O1X right now. I have a Soundelux 195 into a Great River pre into a Distressor for vocals. I really want to sell my Yamaha O1X. It's a pain in the ass and I hardly ever use the faders. Now, I use my O1X's internal sound card. If I sell it, will I need to buy an actual sound card...or a digital converter? Is a 16 channel digital converter the same thing as a sound card?? Sorry I must sound really dumb lol. I want to be able to send my recorded vocals back into my distressor or a different compressor for further hardware compression. Could someone tell me exactly what I need to buy? So as from now, I have no soundcard/digital converter. P.S, the apogee stuff might be out of my price range...but it still can be considered.
