Hi, I’m new to all of this, to be honest. Lately I’ve been getting back into the world of rhythm/music games. I used to play a lot of Rock Band and Guitar Hero, and I also played Rocksmith with my now-dead SX Strat copy (lol). All of that is what really got me deep into music and eventually into playing music myself.

Now, after more than 15 years, I’ve started playing again, but this time using YARG, and I’ve honestly been fascinated by it. The only thing is that after downloading every song I could find (around 8,000 songs), I’ve started feeling the urge to create my own songs.

After watching hours of tutorials using Reaper, Moonscraper, and Editor, it seems to me that Editor is the most complete option for my use case, which is simply creating songs for YARG/Clone Hero. I was also surprised to find that it works on Mac (even if it’s a port).

The problem I’m running into is that when I click “New” and then try to import an audio file, it won’t let me select anything, not MP3s, not FLACs, or any other file type, since everything appears greyed out.

I really appreciate any help, and sorry if I haven’t explained myself clearly, it’s something that’s been frustrating me (and I haven’t even really started yet, haha).

For some longstanding (and potentially obsolete) reasons, the Mac build was never released with LAME or oggenc, but here is a package that will install those if your Mac computer doesn't have those utilities installed already:
