I have a pretty annoying issue with FL Studio. Basically, sometimes happens that certain notes I play start to sound strange and wobbly, and it doesn't seem to be related to a single VST. It sounds like this: http://vocaroo.com/i/s0agtQPNIOYV.
I tried fiddling with every setting of FL Studio possible, but it doesn't seem to be an issue related to buffers and stuff like that. The strange thing is that a new project doesn't present this issue, and it happens, it seems, randomly.
I tried reinstalling FL Studio, but to my surprise the issue stayed in the same project I had the issue before. I think it may be some setting I accidentaly change midway, but I cannot find what triggers it.
