I have a detune issue with AU plugin inside Logic Pro X for certain sample rates.
So when playing with 44.1k sample rate and all other multiples of that sample rate then there are no issues with plugin being detuned - playing note C3 is correctly produced as C3.
If I change sample rate to 48.0k then playing note C3 produces C#3 - half step detune.
Now this only happens with AU build on the plugin inside Logic Pro X.
I have tested with REAPER and Live and no issues at all - for both AU or VST3 builds.
Any ideas what might be the issue here?
