Director certainly needs to be updated to 1.21 (which is available). I’m not sure about the MixPad and OneMix, but I assume those would need to be updated as well and likely available for download.
I use Mixing Station Pro and it will warn you that the firmware versions are not matching the app version, but at least with 1.21 you can still connect and everything seems to work fine. When we went to 1.20 (from 1.12 or whatever the old version was), the Mixing Station Pro app wouldn’t even connect until the app was updated which took a couple of weeks. Keep in mind that Mixing Station is not associated with Allen and Heath in any way, and the developer has to make the appropriate changes to his app after the firmware is released and he can figure out what needs to be changed. So the delay is expected. I’m just glad that the 1.21 update was small enough that it doesn’t seem to effect the usability of the Mixing Station app.
