Apogee Duet, Mavericks, Volume control keys!
For those of you who are using Apogee Duet (Firewire or USB) and just UPDATED to Maverics - DONT INSTALL NEW APOGEE DRIVERS!
The reason is - once you install new driver, software volume control keys (on your keyboard) wont work! You will have to use DUET's knob which is not always confortable.
There is no fix for this yet and maybe wont be, because of Apogee "great" costumer support - (such problems with DUET first appeared in Lion)
If your drivers from Mountain Lion (or older) works fine, dont update it or reinstall it. You will be unable to install previous version in Mavericks.
If you're the one who installed fresh copy of Mavericks from USB Flash, i dont think there is a way to fix the problem. One thing that i didnt try was using Pacifist to force replace driver files.
Hope this message was helpful 😉
