Hi Deep Groove,
Welcome to the MacProVideo forums.
The term you're referring to is called "latency". (the difference in time between when you create a sound signal and when you hear it back through your monitoring system).
There are a few things you can do to reduce the latency:
go to Logic Pro > Preferences > Audio [Devices]
In the Core Audio tab you'll see a pop down menu for I/O Buffer Size.
It's worth experimenting with the settings here bearing the following in mind:
- Lower buffer size setting = less latency but more strain on your mac's cpu.
- Higher buffer size = less strain on your cpu (thus better for mixing).
Generally a buffer size of 64 to 128 is ok for most people, but do try 32.
If your system struggles to playback - or you get error messages, consider taking away any latency inducing plug-ins on your audio track (e.g. limiter, adlimiter, reverb etc)
If you don't want to hear any of the built-in effects while recording uncheck "Software monitoring".
Let us know how you get on.
The Logic 101: Core Logic 8 Tutorial is a really really excellent place to start if you're starting out in Logic:
