I'm using Logic 9 with the Apogee Ensemble on an Intel MacBook. I am encountering random digital "pops and clicks" on vocal recording. I've done a lot of choir work recently, and these pops and clicks appear, usually, at the end of fairly intense high notes. The "residue" is definitely not being caused by the mics being overloaded. I have experimented a bit with the IO Buffer size, but, nothing seems to change. Might something be wrong with the Apogee? I can't believe this is normal.

Hi dfraser, Try unplugging the Ensemble, restarting your Mac, downloading the latest drivers and replugging everything in - do you get the same issues? Is the I/O Buffer Size at 512 or 1024 when playing back? What's your CPU meter (in Logic) reading during these pops and clicks? Are you running Logic 9.1.3 and OSX 10.6.5? How much ram does your MacBook have and what processor speed is it? Do you get the same pops and clicks if you change the audio driver in Logic to the Built-in and use headphones to monitor? Thanks Rounik
