| I am happy to know the reason and solutions. Thanks.
But... I do feel that there should actually be a .csd (like Xanadu) loaded in by default snd maybe mic off too so that the very first time that someone tries to "run" CsoundQt... it works!

Portaudio correctly reports an error whereas coreaudio accepts the 2 channels input and provides an empty second channel as input. In order to deal with that, uncheck the number of channels in the csoundqt settings and set a corresponding "nchnls_i=1" in your csd.

I think it has to do with preferences and it being overridden to always use -iadc. I don't believe this is something I set; is this the default? If I set it to none (i.e., blank) in preferences, the examples that don't use audio input run fine.

I saw the Spectrum Analyzer example (from Useful examples) and it had FFTSize as a widget. On the screenshot for the release, it looked like a dropdown was a part of the display, so I wasn't sure if it was a built-in feature for window sizes or if that was a separate widget that was overlaying the display in the screenshot.
