I'm looking for a way to route the output of irealpro into logic pro x. From there I want to use Source Connect Nexus to send into zoom while I am teaching lessons. Anybody got any ideas?
Loopback might work for you since you are wanting to route audio in various ways. There is a trial version for testing. (There presumably are similar apps.)
And Apple provide the option to create aggregate devices (Utilities>Audio MIDI Setup) if you have audio interfaces involved (e.g. external microphone)
I am a long time user of iReal Pro and I often use iReal Pro songs as backing tracks when recording in Logic Pro.
Last week, I uploaded an improvised guitar solo over rhythm changes video to YouTube using this process. This week's YouTube video video is a walkthrough demonstrating how I do this. I have also created a blog post walkthrough for those who prefer reading rather than watching. Hopefully the content will be helpful to other iReal Pro users and will expand your creative possibilities.
