Mostly! Oakboard Mini and Oakboard Slide Duo work correctly when plugged into mobile devices. But while Oakboard Floor Vista's foot switches also work on mobile devices, its OLED screen will not display any information. This is because Floor Vista's OLED screen is compatible only with Taz, AbleSet, and SETLIST running inside of Ableton Live on a computer.
Overall, make sure you're using a USB adapter that provides sufficient power to USB MIDI devices, such as Apple's Lightning to USB-3 Camera Adapter. We have also found that this lower cost SUNTRSI adapter works.
If you want to run mobile devices redundantly, we can confirm that Slide Duo's two USB outputs will work as expected.
