I'm not too familiar with Logic X Movie applications but, I have worked with earlier
versions of the Logic workstation family for a number of years. Correct me if I'm wrong
but, from what you said about using Logic for movie scoring or sound design purposes, you
probably have quite a few samples, clips, and processors running simultaneously? If this
is the case then, it seems to me that your computer's processors and or "Logic's"
processors are being jammed up with too much bit data. Which will overload your CPU
system, causing it to lag hard. I'm not sure if your aware of this but there are a few
different methods to help alleviate some of the lag issues you are getting in your
Freezing Tracks- You can free up some your systems processors by
freezing certain tracks that you are not currently editing or do not need at the time. You
can enable a specific track to freeze by, Right-clicking on the track's tab to the left
(Where you find the track Mute, Solo,ISO Input and so on). a menu will appear by your
cursor prompting you to make a selection. Around the third menu prompt, you should see the
words "Freeze". Go ahead and select the function (I'm not sure why I got an error -43 but
just continue if you do see this and Logic will begin to process the track and freeze it).
This function allows Logic to freeze and processing being used on this track (Keeping any
effects you might have), and Logic will reference the audio track that it has bounced to
free up space for more processing.
Buffer Size- If you are in the process of
recording tracks in your session, then allowing the amount of samples being buffered is
crucial when working with a lot of tracks in one session. Typically, Logic defaults the
I/O Buffer at 256 samples. Raising the samples to let's say 1024 is most ideal for
recording because the higher the I/O Buffer's sample rate the more latency it puts on that
incoming signal, which in return frees up the CPU's processors.
This may also help you manage your session's processing. You can view and access a meter
that allows you to see how much process you are using til the system overloads.
Logic System Performance: Go to: Options > Audio > Click "System Performance" = a
meter will appear you can use this as a reference tool during your sessions. You can also
always rent a Mac to use during your project that has upgraded sound and graphics cards
plus a RAM upgrade. you can take a look at some here: Mac Computers
this helps you out! Let me know how it goes with your movie session.
