I would like to ask for advice about a problem I am having when recording vocals. I am using Logic 9 on a Mac Pro, with a Lexicon I-ONIX 42S Audio Interface. The problem Iâ€™m having, is that when recording vocals, the vocal sound that arrives in the headphones for the singer, is really horrible. It sounds â€œchoruseyâ€ and â€œthinâ€, and more than one vocalist has complained about it. The main singer I work with says that she feels like she is â€œfightingâ€ the sound and trying to compensate for the poor vocal sound, and as a result, sheâ€™s not comfortable with her singing. When I listen to the vocal sound in the headphones, to me it sounds like there may be 2 copies of the vocal signal with a slight delay between them, which is producing the chorusey effect, or maybe the signals are partially cancelling out, causing the â€œthin â€œ sound. My first thought was that the two signals might be the direct hardware monitoring signal of the IO42S mixed with the software monitoring signal coming from Logic. The IO42S has a Monitor Mix control on the front panel, and according to the manual, if this is turned fully to the right, there should be no direct monitoring through the audio interface, I should be hearing only the mix coming from the computer. Thatâ€™s the setting I use. If I speak in to the mic and turn this control from left to right, in the hardware monitoring position the voice sounds normal, and in the 100% software monitoring position, it sounds unpleasant. So it seems to me that the routing through Logic is what is producing the strange sound, but having played with many settings in Logic and looked in the manual, I canâ€™t seem to solve it. Any ideas what might be wrong here? Thanks.
