Logic Pro 9 Preference Settings

Hello,

If I start Logic up without my Firewire Audio Interface plugged in (Focusrite saffire pro 40) then, with interface switched on, I plug in the firewire and go to Preferences / Audio to select it as the input and output, it doesn't appear. It is only there when I boot Logic after I plug the interface in. Is there any way of selecting the input/output when Logic is already up and running?

Thanks
Neil

Not familiar with Focusrite products, but it sounds like it may be just the way it is - maybe a driver issue.

One thought - have you tried plugging in the Focusrite and then turning it on?

Thanks Doug,

I was wondering if this problem that I describe is true of all audio interfaces. ie that Logic will only recognize them if they are plugged in/switched on before you boot logic. Is it not?
2nd. Do you mean: Logic on, plug in Focusrite when not on, then switch it on? I'll try it.

Neil.

Logic recognizes all the connected MIDI devices when it launches. You're going to have to connect the interface before you launch Logic. Is this a hindrance?

I'm thinking my Apogee gear all is recognized by Logic if I swap/add while Logic is on. And I just tested it on my Mbox, Logic is running, plugged in Mbox, Logic recognized it. So it's very possible.

Yes I do - perhaps that will work.

Yes, it's a hindrance because I often work with logic independently from the interface then I always have to shut logic down when I plug it in to record or mix. It's all a bit clunky.
 
A warning: the firewire port is always putting through a heck of an electrical charge, and you can break your FW port if you aren't careful... It's like releasing a drive by trashing it before you remove it.

in fact, M-Audio specifically warns against doing this with their audio interfaces.

I've discovered that if you're using a FW400 device with a FW800 port/adapter, the danger of hot plugging (what george describes above) just isn't there. It has something to do with the way the pins are arranged on the FW 400 port/connector. I hot plug my FireWire Solo every day, several times a day. Doesn't hurt it at all.

Old habits, but I would connect the interface to the computer before turning it on.

Hot-swapping my USB Apogee One causes Logic to loose connection with the interface driver even though the OSX Audio MIDI utility will acknowledge when the Apogee has been be reconnected.
