Everyone abuses a new tool when they first get it....
You know you've hit the bottom when someone finds you in an alley behind a real recording studio using autotune on your ipad or worse, your iphone to tweek your latest vocal recording.
Seriously, stop using the one click solution on Melodyne and just say "NO" to presets. With Melodyne, do your corrections manually, listening to the track and fix it one note at a time manually and only if it needs fixing. I used to use the one click autofix but I managed to kick that nasty habit and now use it where and when it's required to improve the performance.
As far as the presets in the "turd polishing software"...... learn what it is doing and if you wanna use presets, at least make your own as starting points.
