Latency.. . . . . . . .

I'm having crazy problems with latency ! ! ! !!!!

Ableton Live 9 Suite 9.1.7
RME Fireface UCX on MacBook Pro:
2.9 GHz Intel Core i7
8 GB 1600 MHz DDR3
OS X 10.9.5
500 GB SSD...

Can't seem to find a setting that works- I'm just trying to rec some vocals over some beats...
Everything is fine when recording similarly in REASON. 
Any suggestions?

    Same issue here. Hope there will be a fix on this.

    Might need more information about your set… Like are you using 100 plugins and CPU intensive instruments? How many tracks, clips, lanes etc. ?

    Try different cables for everything. Isolate it to a mic issue too, use a different mic.

    Try freezing all of your tracks then try recording. Also try turning off all of your EQs and plugins.

    If you've completed instrumentation on the track… Bounce the entire track (no vocals) to wav or aiff. Create an empty live set and add the bounced track to the session or arrangement view. Set your Preferences>Audio>Buffer Size to something real low and try recording. You'll get almost 0 latency. Then bounce the vocal track and import into your track with instrumentation

    Could also be the In/Out Sample Rate you're using and Bit Depth. Unless you're recording a master piece, I doubt you'll need anything higher than 24 Bit Depth and a 4800 Sample Rate.

    I think it has something to with the way you use live… I use a MacBook Air on 10.8.5, running 4GB RAM, 1.7ghz i5 with only 128GB SDD and I never manage to have any latency issues. It's going to be hard to determine a "fix" if we don't know the parameters of your live set.

    In order to keep latency to a minimum while tracking, I keep my buffer to 64 samples at 48k/24bit. With my current setup that gives me about 8-9 ms of latency, and I am quite comfortable with that. If plugins start causing a problem (popping and crackling) I print or freeze tracks. It's a constant juggling act.

    I suggest you fiddle with this buffer size setting until you find a good balance for yourself, based on the sample rate you like to work at. 

    A few plugins (and sometimes a bug in MAX) render this buffer size variable useless so I get rid of them or restart the software as needed. For example I can only use Slate Digital Tape Machine plugin when I'm done tracking as it bumps up latency to unusable levels. This is fairly specific, however ,and I haven't seen it in many other circumstances.

    The buffering takes place in RAM, if I understand correctly. Unfortunately, plugins also need fast memory to function and therefore are in competition for this finite resource, causing stuttering and crackling at low buffer settings. The more RAM you can pack into your computer, the better off you are to avoid RAM traffic jams. Ableton 32 bit can use up to 4 gb of RAM while 64 bit gives a potential cap at an American 16 billion gb of RAM. Currently most Macbook pros are spec'd to handle 8 gb but many are having success with 16 gb, which is still affordable.

    I had one day with crazy latency - it turned out that live was doing an update in the background and it was making the whole system unplayable.  But no warning messages that it was going to do this - just switched it on to show a friend, and made me look like an idiot.  Just glad it wasn't for a show!
