I mean if you hover over the item in customization it will tell you what it does . <| sep |> Yeah , not sure how people got this offer to work , jet might cancel a lot of the people who ordered doing this because it was a website error . <| sep |> With Razer Synapse when i turn off Raw input i have like 30 sens . 1800 dpi <| sep |> This is going to be a bit of a novel and a braindump , because I want to spare you the pain I went through . I also hit the character limit so this is split up into a comment chain . Hope this helps . The most important things are in rough order How good is the song ? How good is the performance ? How good is the sound in the room ? How good is the sound of the room you ' re recording in ? How good is the arrangement ? Is the signal clean ? Are the takes edited to give you the best possible take ? Does the mix gel ? I can ' t stress enough how much more important what happens before sound hits the microphone is . If the song is a dud , it doesn ' t matter how you record it . It ' s going to suck . If the performance isn ' t good , the quality of the recording doesn ' t matter . Meanwhile you can get away with sonic murder on the recording side if the performance is stellar . If your arrangement is a mess , it ' s going to be a bitch to mix . If your arrangement is great , the song mixes itself and sometimes you can get away with basically no mixing at all . Sound quality doesn ' t matter all that much . What matters is the performance going in . You know hozier ' s take me to church ? The vocal on that is a demo take , because that was the best take they got . None of the studio takes were better . The song is the king . The performance is the queen .
