Logic question

[Brandino221]

Sup guys. Ok..I got am going to be taking my system for a big session. I have not recorded a band on my system yet. I got a dual 2.0 G5 and 1.5 gigs of ram with a motu hd192.
I get a little latency when I record vocals now. If I get more ram will the latency go down? How much ram do u think I should get for a modern style recording (lots of tracks)?

Thanx

[gramps]

what sample rate will you record at?
what is your cache setting?
i would do at least 4 gb ram?
don't strap anything across the master outs. this is a major cause of latancy with logic when recording.

Well...I was thinking to record them @ 96.
I was looking about the cache setting....I found that in video at 40mb. But I am not useing video.
Now on my computer it says this..L2 Cache (per CPU): 512 KB
and like I said..I have a G5 dual 2.0

SO will more ram kill latency??

[Wolfgang]

What are your buffer settings ... that is most likely causing the excessive latency.

No, RAM will not cure it. Although, i would suggest more RAM for other purposes.

There are too many variables to give you a silver bullet answer ... list more specific details about your 192 settings inside Logic and outside - and how simulatanous tracks ... any inline effects, etc, etc ...

ok...
buffer size= 512
Recording delay=0
Max number of audio tracks=20 (but I always change that as the session gets bigger)
64 busses, universal track mode, larger disk buffer, are not checked.

Process Buffer Range=medium

I am also recording in AIFF

It's the buffer size you should change. 128 is decent. Lower figure = less amount of latency.

Good luck with the recording.

Yea..I know that the lower the better. But even when I had it low I still had some. I don't know..I got to do another test.

Hi, if you use the Motu 192 you should use the CueMix application. Works great, no latency at all.

[Wolfgang]

Well, he should have enough horsepower for 128 --

As for CueMix -- yeah, not latency, yet, i always found it inconvienant - i had a 192 and 2408mkII chained together - going back n forth between CueMix and Logic was too clumsey for me in intense sessions ... but, it is cool to monitor off the card if you want to jump the hoops!!

Also - reduce you busses if you are not using them ... for that matter, reduce or eliminate anything you are not using, as it does increase processor overhead - even if you are not utilizing the mixer object.

[Brandino221]

so what do I need to do to record 12 trax at once? how should I set it up in logic?

[echorec]

Put track 1-12 in record mode. Input 1-12, no output in Logic. Launch CueMix and unmute input 1-12 and set the monitor levels to taste. Make record.

I think CueMix is very convenient and I do many band recordings with many tracks recorded at the same time.

Where is the latency?
in your monitoring or when u play back?

if its monitoring, then buffer is the only setting that helps. - Or use direct monitoring of your Motu.- What i do for monitoring is: use the direct out mix of my MIO 2882, and only some sends in logic for reverb effects while monitoring.

is it in playback? then:

It cant be buffer settings.
Do u have Plugin delay compensation turned on?
Look into the audio settings and turn plugindelay compensation - off/or only tracks instruments while- recording. if u have PDC switched on on all tracks(incl buss/mast) while recording, strange things can happen to your timing.

Oh, and for RAM:

Logic cannot acces more than 2,5 gigs.
So putting more in there would be a waste.
Only programm i know of that really uses more is final cut.

Yea..it's on recording. I will check those things too. I hope cue mix is cool..cu I have never used it. Thanx for the help guys.

just disable software monitoring

then use cue mix

what exactly do you mean by that, just out of curiousty?

[gramps]

i don't know where my first answer went but here's an abbreviated version. i had two versions of a song. both songs were 40 track with 60 plugs and 9 soud designer IR's. one had latancy issues when tracking and the other didn't. after hours of self belitttling effort i discoverd that song b had one more plug on the mains than the other. after disabling the 3rd plug that latancy disappeared.

hope this one posts
