Hey everyone, I'm new to this forum and to Logic Pro so please bear with me as I try to describe my problem. I recorded a guitar sample with my mic/mixer into logic and the playback was fine initially. When I added a software synth (the Native Instruments B4 II synth to be precise), the playback on the guitar track dropped significantly in quality, as if I had put a low-resolution filter on it. When I remove the midi track the audio track resumes its previous quality. I thought at first that I only needed to increase the buffer size. I increased it to 1024 samples (from 256) which fixes the problem until I try to record with my midi track. I am running Logic Pro 8, version 8.0.1 on a 2.2 GHz macbook Pro. Any ideas anyone may have would be really appreciated. I'm at a loss and just exploring the program randomly at this point. Thanks!
