Sorry for my poor English - I come from Poland, but I hope you will understand my question.
I would like to record music from my Krome in high or more than medium quality. I want to record it to my laptop so it is obvious that I need an external audio interface/sound card.
I don't know anything about this kind of recording, I don't know which kind of audio interfaces I should choose. I am considering to buy something like ALESIS Multimix 4 USB or Behringer Xenyx Q802USB. But still don't know anything about quality from these devices.
I would like to record solo piano songs, or 10-track multiple-instruments songs.
I would like to spend up to 400$ for audio interface and cables.
Could you recommend what would be the best choice? Or maybe there is other way to record music on computer in good quality?
Last question: which recording software do you recommend. I was using Audacity but the quality of recording was poor (I could hear some quiet noises)
Thanks a lot for help!
