I use this pedal with Bias FX as my 'compact' bass pedal rig when I don't want to take my main pedal board. This just slips in the top pocket of my gig bag and i've got access to decent enough compression, overdrives, octave etc with only my phone. It takes it's power from the phone itself (although does have a splitter to take USB power at the same time) and i've used this for hours with no real apparent hit to phone battery life. Latency seems pretty much non-existent using an iPhone 11 Pro. The midi switches program easily within Bias FX - I have bank A (green) set up to switch on and off individual pedals in each chain, Bank B (red) set up to toggle up and down patches and the turn on and off the tuner, and Bank C (blue) to toggle up and down banks (and the tuner again). Built quality seems pretty bulletproof. All in all does exactly what I was looking for!
