Hi, unfortunately I don't have a Mac device, so I can't confirm this, but setting up the audio configuration in MallMuzik on a Mac probably doesn't work well.
You need to use OCR for VO and be very lucky to set up audio devices for VDJ.
I would try the following workaround.
You need to find the settings.xml file in the virtualdj folder. Edit this file in Notepad, and you'll find the audio configuration section at the beginning.
Try copying and pasting the configuration for your own hardware.
Set up one device for test configuration 1, for example, the master Reloop.
Then edit the settings.xml file by copying this device to the second, normal configuration 1, and save the changes.
Then return to MallMuzik and, for test configuration 1,
first remove the master Reloop.
Then set up the MacBook headphones and edit the settings.xml file again to copy this device to the normal configuration 1.
Repeat the steps for the microphone and other devices. Maybe this slow process will allow you to build a Normal1 configuration that has all the necessary devices.
The entries in this section contain the system IDs of the audio devices, followed by the channel assignments and the input/output type.
You can even change the name to "headphones" instead of "master," and maybe it will work.
If the audio devices are recognized by VDJ, it should work. Good luck and best regards, Zenek.
