Autotune programs?

Might try this one

I have the UAD version of AT and it doesn’t have the graphical portion - which makes it either where it works for singers that are close and don’t have weird turns or grace notes...or it just doesn’t work. I’m surprised Melodyne is crashing. I don’t think I’ve ever experience a crash in the years I’ve used it.

It's the only plugin I use that crashes.  It's the only thing that's ever crashed Reaper in the 15 years I've used it.  It just locks right up sometimes.  The GUI for it also won't resize correctly and the controls are always off the screen and I'm always having to scroll the window to get to the bars to scroll Melodyne.  That and the keyboard controls are mostly opposite of just about everything normal.

I spent an hour last night tuning something only to have it freeze up.  Everytime I hit save as a profile it takes up to 30 seconds to actually do something.  If I try to close the window during that time it'll do nothing, or it'll freeze the program completely.  If you're used to working quickly, it's ridiculous.

Sometimes the detection will work, sometimes it won't.  Sometimes switching detection will work, sometimes it'll just randomly switch back to default.  Sometimes when I click on a blob it'll switch between corrections and I won't notice and I'll have to back out of what I just did, but sometimes when I hit "undo" it'll randomly undo everything I had done in the last few minutes..  or not.

And I thought for sure it was just me and there must've been something I was doing wrong but no, there are forums full of fed-up folks complaining about the same things I've been dealing with for years.

I spend way too much time fiddling with the program to make it work.  It's powerful, but I just want to work, not spend half the time fucking around with the program.

I could give a dozen suggestions to Melodyne and it would make the program unbeatable, but apparently they don't listen to their userbase.

In before the obligatory “just sing in tune.”

I was tuning DI from a guitar that was slightly pitchy..

I do the same thing - probably from back in the day when that was the only viable option as it used to lock up PT on a regular basis when it first had the option to run as a plug.

Print an instrumental, export what you need to tune and use it as a stand alone plugin.

I’ve had some bugs with them in the past but nothing like you’re describing. I’d be pissed off too if I had to deal with that bs!
