I am using a Line6 KB37 together with Logic X 10.0.7 (OS X 10.9.4). The KB37 (newest drivers and firmware) is my audio in- and output and midi device. Everything works fine except two keys on the KB37 which are not triggering sound (e. g. as a software instrument). It's F3 and B3. Instead of triggering sound some weird movement on the faders are happening. I can trigger those two tones without a problem drawing them into piano roll. Also GarageBand has no problems at all triggering every tone on the KB37. It clearly seems to be a Logic Pro X problem. And my Roland FP-7 masterkeyboard (also connected via USB) triggers all midi notes correctly, too. It very much seems to be a midi-misunderstanding between the KB37 and Logic, but I have no idea where I can map the KB37 correctly.
Any ideas how to solve this annoying problem are more than welcome.
Thanks,
Marc
