Midi / USB drop out since Lion upgrade!
Hi all, i have had great responses and success in the past with this forum, i really really hope this will continue.
I have been gigging using mainstage 2 and a M-Audio Oxygen midi keyboard controller for a few years now and until lately it's been fantastic. I will never go back to a stand alone manufactured synth. I am using a macbook pro, 2.93ghz with 8 gb ram. I initially upgraded from snow leopard to lion when it was launched but had to go back as Creative hadn't any lion drivers for use with my emu 0202 audio interface. Last month i found that they had done them and i re-upgraded to Lion. Since the upgrade i am experiencing Midi drop outs. This is to say that whilst performing i get an error message saying something like midi input device no longer available. This has happened a few times now but last night (new years eve!!), not only did i get this message which i sorted with a reboot but a few minutes later i had a midi note hang and i noticed that there was no longer any usb supplied power to my keyboard. The answer again at this stage was a reboot.
I would ideally not like to reinstall snow leopard as there are quite a few great things in lion which i would miss, but obviously if i can't resolve these issues i don't see that i have any other choice.
Any possible suggestions as to what may be causing these problems will be very much appreciated.
Thanking you in advance
Mark
