I recently purchased the Focusrite pro 14 and it was working just perfectly until yesterday. Now whenever I try to record vocals the track has a flange/auto tune sound to it and is incredibly annoying. I have closed and reopened Logic, created new projects, unplugged the interface, tried different mics yet nothing has helped. I'm wondering if anyone else has had this problem . Here are a few additional details: sample rate is 44.1, the buffer size is 256, I have only a usb external hard drive connected to the computer. Thanks.
