Bluetooth & Logic X problems

Greetings all,

i have a frustrating problem that I can't seem to find any support for. I have a late 2013 iMac 3.5 running current logic x. I recently purchased bluetooth headphones (AKG K845BT) for the purpose of freeing myself up during tracking sessions. I figured this wouldn't prove to make any issues for m. Because its 2014, and bluetooth has been integrated into Mac for a decade now.

MY challenge is this, when I select the audio interface to handle the inputs, and the BT headphones as the output destination, I lose all input. I double check that the proper I/O's are chosen, and still no luck.

I've vie played around with aggregate, but haven't really came up with a fix.

Any assistance or guesses on this problem would be GREATLY appreciated.

Thanks all!

Just a guess......

Input and output have to have some kind of digital sync so they are locked to each other, from what you describe the Bluetooth audio device doesn't use a standard digital audio clock and the Input Device can't find a digital clock to lock with. By Lock I mean sampling frequency. 44.1, 48, 96kHz...etc. You should be using 44.1 or 48 with Bluetooth, at least those have the best chance of working. Bluetooth is not a high resolution protocol.

What audio interface are you using?

Try creating an Aggregate device using the internal audio. Make the Built-in-audio Input the master the Bluetooth device slave and set the BT device to resample.

It's also worth noting that what might be happening is the built in Mic in those headphones is 'taking over' the input.... This is a 'feature' that I have seen cause this issue due to the way NFC and BT is implemented on certain BT cans...

Thanks for the reply Pancenter. I am using a M-Audio Mtrack Quad.....and I am slowly regretting the purchase. I will try your Aggregate suggestion and let you know if that fixes it.

You are correct to mention this. As soon as I choose the AKG's as the output, Logic defaults the input to the AKG's. I caught this the first time I attempted to track wit them, and am quick to check this each time I play around with it.

Ok, but don't use built-in audio, use the M-Track as the master.

Although.... it may be worth a try to include the Built-in audio as well.

Unfortunately, Bluetooth is not that good at real-time integration so there may be some lag as well.

Still no love.....I tried all.....Im beginning to think that there are some serious limitations to M-Audio beta drivers for Mavericks.

All I want to do is use my M-Audio Quad box to track inputs WHILE i monitor the records with my bluetooth headphones....Its 2014!?! Is that an ability that is not available yet?
