Help finding contol point compatible with Krell Connect

[stefano_mbp]

... another tip, a little more complex

you could try to install Bubbleupnpserver where you like ... maybe on the same nas/pc where minimserver is running.
If Bubbleupnpserver will see your Krell then it will give it OpenHome capability therefore it will be discovered through Bubbleupnpserver by a lot of apps.
Bubbleupnpserver is free and can be downloaded here ... https://bubblesoftapps.com/bubbleupnpserver2/
In case of success you should try Lumin app (iOS 9.3 compatible too) ... it has a very fine user interface
