First, I must say I like the AUFX suite very much. I tried one, and got the rest when I saw the quality of the sound adjustments. Thank you!I am still trying to suit it to my specific purpose, which is basically as a microphone voice pre-processor.Using iPhone4S version 8.1.3. Also using Bose QC20 earbuds with a great quality inline microphone.This works fine. When I plug in the earbuds, IOS switches automagically to use the external mic.AUFX uses the external mic routed by IOS as input. All is well.But for my purpose I want to separate out the mic and headphones channels.Or, I may decide I need to use a completely different microphone than either the internal or the earbud/inline.I got a split-out cable with F 3.5mm 4 Pin to M 2x3 Pin 3.5mm, for my head set w/mic.I have another split-out cable with M 3.5mm 4 Pin to F 2x3 Pin 3.5mm for the iPhone.This arrangement also works fine. I am able to feed the headphones from a mixer, and feed the external microphone, to the iPhone.But then IOS does not detect the input connection as a dual route device, and uses only the internal iPhone mic for some apps (AUFX), or both mics for other apps, like the phone, which is quite annoying.I have read that since iOS7, this functional setting (routing) can be selected by Apps, specifically "The extended API is in the AVAudioSession class", "AVAudioSession - setPreferredInput"Since all AUFX Apps have an input selector which can toggle L-R or Both (which has no affect on a mic input), would it be possible to add the ability to select internal/external mic inputs ?Selecting Both would not be advantageous to me, but perhaps to others it might be.The other consideration for using this excellent tool suite would be as a FX processor from a typical mixer (ie Behringer).This also would require such routing control. The mixer's mono FX send into the IPhone to show up as an external audio input, then the output fed into an AUX input on the mixer, would add AUFX effects into the entire mix.Having this ability to select internal/external mic input would certainly make your apps suite a solid tool in my studio.I hope this is a suggestion you can consider.I will eventually move this voice processing function to the iPad, but that's currently running IOS6.This tool may be what moves me to upgrade the iPad, if we can work out this audio input routing issue. :)Thank you for your great product.
