Hey guys. I recently had a thread where I wanted to get advice for portable recording and jamming. in conclusion I decided to buy a audio interface and some kind of software to get the sounds I want and record them. My main interest is in Focusrite Sapphire series but I'm a newbie in this area and need some advice. I've checked 3 models: Solo, 2i2 and 2i4. What's the main differences between them except the obvious 2 input on bigger ones? I'm not going to record multiple stuff simultaneously, I think so 2 inputs doesn't matter for me. I'm leaning towards Solo cause its so compact. Are there any drawbacks on Solo witch aren't in its bigger brothers? Also,y ou can always suggest me some different interfaces.
