Hi. I'm looking to re-setup my home studio. I was for years working on a G5/mbox2mini/protools 7.4LE. I'm on a 2010 Imac now running Mavericks. My need is to record guitar (line-in) and vocals (condenser mic) and to produce audio works for radio and to have my studio monitors working again. I'm leaving Protools, can't afford the latest versions and it provides more than what I need. The entry level Fast Track Duo is in my opinion under par. Planning to work in Garageband ftm and to keep my options open on software. After a good interface that meets my needs well but not overkill, under $300. There are a few that have caught my interest, Behringers Uphoria UM204. But on further research, seems people have had problems installing it. I'm aware to, to be sure of compatibility with Mavericks. Any suggestions appreciated.
