iPeng 9.3 with the Roon playback support is now rolling out on the App Store.
I’ll write a bit of a bigger announcement in the coming days but just wanted to let you know here since this has been going on for quite a while.
Please let me know how it works for you.
Just to be clear in case you don’t have iPeng, yet: you’d need both the App (iPeng 9) and the “Playback” In-App-Purchase since iPeng is essentially not a player app but a Squeezebox remote control app.
