I just bought a USB Samson C03U microphone, and I'm attempting to record a vocal track in Logic Express 7.2. I've adjusted the Input Volume in System Preferences -> Sound, and experimented in Logic quite a bit. I've noticed that on some high notes in Logic Express, it starts to clip a bit. I've also noticed that in Logic, even if I adjust the volume knob on my vocal track to reflect a lower volume, it doesn't seem to affect the microphone sensitivity. I've even switched the microphone to -10db, and I'm still experiencing some clipping. Does anyone have any experience with this USB mic and Logic? I'm not able to find a decent way to control the sensitivity of the microphone....help!!!
