@ulrik @d-healey Major lesson learnt! I had been doing some tests with building a swift app on my iPhone and somehow it was still doing it with HISE! So always double-check if you have any outputs activated
in Xcode>Window > Devices and Simulators.
Although now I did find a major bug on an instrument we are building, so I will do a separate post on that.
Thank you for all the great help!
