I’m attempting to update the firmware and reinstall the default modes on my MM using the mobile app but I keep getting a Transmission Error message. I’m running IOS 26 Beta 2 for iPhone.
As an alternative, I was able to update the MM from my iPad which is still running iPadOS 18.5.
Has anyone else experienced this issue with the beta version of IOS 26?
Hi Keith,
I’ve sent you an answer via email.
I’m also having this same Issue in addition to having EEPROM INVALID displayed.
For the time being I’m completely unable to use the MM
Yes that’s what happened to mine. I was lucky bc I still had iOS 18.x running on my iPad so I was able to reinstall the firmware using that. I got it working again and haven’t tried to reconnect with iOS 26 even tho it’s now on version 5. It was version 2 that wouldn’t connect for me.
Please send an email with the details to support@singularsound.com, thank you.
I had exactly the same issue. Unfortunately. I updated my phone and iPad and apple won’t allow us to rolll back. I used my daughters ipad to get the firmware and default mode updated which sorted the eeprom issue but would be great to get the full functionality on my own devices. I’ll send an email to support.’thanks..
I had this issue crop up on the iOS release, which wasn’t a beta. I ended up borrowing my kid’s iPad, which still runs the older iOS, to update my Midi Maestro. I’m sure Singular Sound will update the app to work soon.
Hi, Just wondering if there’s any update from SS on this ? I assume this issue will grow as more people update to ios 26. I’m enjoying the unit but not getting the full value out it as I can’t play around with the custom mode. Even a heads up and confimration that it’s being investigated would be much appreciated. Thanks.
Hi there, it is currently being investigated, thank you for your patience
There is no estimate for a fix at this time
Since I’m on a month break from gigging and I got the all clear from OnSong to update to iOS 26.1, I updated my main iPad. There are definite Bluetooth connection issues with the MM on iOS 26. I’ve tested with 2 different MMs and my iphone on 18.6.2. The iPad connection drops off after 10-15 seconds which keeps my OnSong midi commands from firing off as I work through a song. Please continue to search for a fix or lobby Apple to fix their Bluetooth connectivity in this version of their iOS
I’m currently having to connect a CME WIDI device into the MM and connect OnSong to the WIDI to prevent connection loss. I’d rather not have to do that.
We are currently investigating this issue and hope to have a fix soon
Thank you for your patience
