Hi everyone I am having a problem with my mic where I sing into the mic and it affects my instrumental sound when I sing, like (blowy sound and cuts the instrumental and makes it sound shit. It’s not me cause I’ve fix this before but I haven’t gotten on my mic for ages and just forgot how to do it unfortunately. I have 2 stations one with my singing and1 with instrumental on GarageBand. Can anyone help me?

like @blondiewales I am a little confused by you problem. Make sure to check the things blondie mentioned. If you sing into the mic look which VU meter shows the incoming signal.
