I found it confusing to set up on Mac- not really Hotone's fault but instructions could be clearer, see e.g. app is required for device configuration but not in day to day use. The Android app required sideloading but there is a Mac App in the Apple Store. Cloud sign on request is presented on every connection but may be dismissed. Tested, including with Headrush Expression pedal, with Ableton Live 12; Reaper 7; Neural DSP Tone King Imperial MKII standalone, using both USB and bluetooth connection
