I almost brought Cubasis 3 a while ago, until I saw it’s £32. They are having a laugh.
I did recently buy an audio app called Hokusai 2. That coast £10. I wanted an app that allowed me to trim out sections of long wav files. Not just split them like Gb can do. We record all our rehearsals and gigs, and normally I’d sit at my desktop Pc and do it in Audition, but I’m doing my best to be more couch based. It’s a really good app, loads of built in effects and some nice pro effects, but I’d still go for GB for multitrack stuff.
