The only negative to my 50/90 workflow of starting new ideas using GarageBand foe iPad is the lack of flexibility with time signatures and tempos. You can’t change them mid-song, and there are only three time signatures built in. I could easily work around that, but then I’d lose the cool segment functionality. Fortunately GarageBand for Mac has more flexibility and options.
Hence the two things I pieced together on the Mac tonight that are both in odd times. Ah, a Prog Rock wannabe.
