sorry use the compressor settings in mic settings and set it to lead and harmony. you vocals will always be matched according to how loud you sing. i set the threshold at 28 the ratio at 5.6 and the noise gate at 60 or less according to how much you hear your breathing thru the mic. This is just a starting point but is should help. If that crown is too hot turn the threshold down to around 18
hope this helps
