Dead end (Hise 1.5)

[hisefilo]

I'm facing a huge issue. I need to add a Custom Settings panel to an old 1.5 Hise project. After doing so, it always shows the "Audio Driver could not be opened" dialog on Standalone compiled. Every single time I open it.

On the other hand, if I port project to Hise 2.0 the "Audio Driver could not be opened" looks fixed, but I loose one of the main components of the sound generation for this project, the "Stereo" Harmonic Filter, which has been ported to mono on 2.X versions I guess.

Any clue @Christoph-Hart ?

I think it might be due to your audio setting. Make sure you've got the correct audio interface selected in the preferences.

@tomekslesicki tried that. But no luck
