I believe I am experiencing a bug with the recently added External Mixer mode on both MacOS and iOS. I am running the latest OS versions and latest DJay Pro AI versions on all devices. I’m using an iPad Air 4 and a MacBook Air M1. I’m using a 4 channel Vestax VCI-400 SE Ean Golden midi controller. I know that the VCI-400 can work as a standalone 4 channel analog mixer. I have the necessary firmware for this and have used it in this way before.
Perhaps I misunderstand how the External Mixer mode is designed to work. What I would like to do is to route the Looper audio only to Deck C or D on my VCI-400 instead of straight to the Master output. This way I could adjust the EQ, Volume and also pre cue the Looper output in my Headphones. The only audio routing options available within the External Mixer setup are ch 1-2 and ch 3-4 (see attached screenshot). From my testing using ch 1-2 sends the Looper output straight to the Master output and ch 3-4 sends the Looper output to the Headphone output. Within Internal Mixer mode I also have the choice of ch 5-6 which is the Microphone input (see attached). There are no options to select the individual Deck Channels A, B, C or D. Perhaps this is a limitation of my controller or perhaps I am trying to use the External Mixer mode in a way that was not intended. Can someone please provide some input or suggestions? Thanks.
