Since I switched the usb from the back of my Minibrute to another midi controller, and back again, the Minibrute will no longer generate sound whenever I start Logic X. If I hold down a key it will work normally until I start the DAW, then it cuts out and will remain in that state even after Logic is closed. I have to switch the brute off and on again to regain sound (Logic must be closed when I do this). It's as though Logic is sending it some sort of paralysing messages? I have reset the midi drivers and tried to connect the brute via Din to usb, but the same thing happens. I'm a little stuck and would appreciate the help if anyone knows what may be causing this.
