So this post made me try something for the first time. I have an app in my iPhone/iPad called Voice Synth. It is an incredibly deep vocoder/pitch corrector and more which I never had a real use case for. I have a Live 3 (although I will test on my 2 which is Keg37 gen, when I get a chance). It literally took less than a minute to load some vocals on a track, send to USB1-2 and create an audio return from USB 1-2 on a new track and I had my vocoder up and running. Some of the presets are outstanding, but the level of control is as good or better than a top shelf vocoder VST.
https://voicesynth.comThe other option I want to try is to just use the iPhone as a microphone and only sample the Vocoded sound from Voice Synth through USB-C. More restricting, but in some cases might be perfect.
I haven't tested the midi control yet for harmonizing notes, but I have previously with some of my synth plug-ins which work great. FYI, the official Moog iOS plugins are a steal and to my ears sound better than the model D MPC plugin.
Hope this helps someone, I am stoked I have a totally new workflow. Thanks for this question. I watched the thread for a few days looking for answers until I got off my ass and did the experiments.
