Okay this seriously rules: my guitaring is going well and at the moment I'm practicing some power chords, and have been just using the metronome in BIAS FX Mobile to keep time. I remembered out of the blue that GarageBand has a "virtual drummer" thing where it'll automatically play a whole drum kit for you with all sorts of different styles and presets. BIAS FX can run in the background while doing this, so I gave it a go and it's SO MUCH FUN! Way better than playing along to a metronome. 🤘🏻
(Yes there's a handful of cocked-up chords in there where my fingers didn't quite get to the right place).
