| This is exactly what I have been doing for the last 3 years, having callbacks callings various data structures, depending on the inBusNumber value. It is has been working just fine with xcode3, xcode4, xcode 5, iOS 4, iOS 5, OS 6 and iOS 7. Now it is only with my app built with xcode6 running on ios7 that I get the saturation, as if the MultipleChannelMixer wasn’t properly doing its “mixing” job like it used. And again it works well with xcode6/ios8. What the hell?
This is most confusing. I have been researching today about issues with MultipleChannelMixers or any unusual parameters that I may have skipped. But no luck.
My solution is going to to forget about MultipleChannel and to do my own mixing in one callback using vDSP functions.
Best,

On the mixer, each channel can be stereo or mono and will call it's callback once per cycle. So if you have one data structure that is supposed to be advanced once each cycle, it ends up getting advanced multiple times per cycle because each channel calls the same callback advancing the same data structure.
