So I fooled around with an app called Ohm Studio last night. Theoretically, you can collaborate in real time on recording projects. My experience differed. For some reason my guitar input device was silent through mu plugins, although it worked without the plugins, or with the plugins outside of Ohm Studio. Latency was crippling. What I did manage to do was export my audio tracks from Logic to Ohm Studio, so if you try it, I'm JustRob there also.
