Welcome to the club, I have sthe same problem using the same configuraiton and V 1.93 firmware of the QU 32 did not solved the issue…
Each time I open a project I have to re attach the four midi banks from Logic to the QU 32
I installed the V1.93 firmware on my QU 32 and I can confirm that it… Does not fix the issue with Logic… Stil the same problem of having to re assifgn midi DAW channel in Logic each time to laucnh the softaware in order to control it through the mixer…
Any news on that subject of Mackie control problems with Logic since last July ? Is A&H strill working on a sqolution” ?
Got the same problem here witha QU 32 Fw 1.9 Logic 10 and Mac Book pro running High Sierra
