Hi all,
Me too i have some strange bugs,
Each time i open Logic i have like Sami the same window issue IAC Driver Bus 1.
I lose the midi signal, when i come to the "VEPRO 3 midi port 1", if i change "All" by VEPRO plugin midi in 1.
Consequently, i'm stuck to use 16 instruments by Instance with "All" port
I used 6x16 multiport template.
Best,
Sam
