I have a very wierd problem. And I try to test it with a tone and this is the result.

Can you guys help me?
Is it Reaper or the plug in or the PC?

I think i should add more context. I saw that when i tried to compress a kick it had 3 cuts in the freq display. I can't hear the problem but I don't think it's normal. After I tested it with a tone generator and it does the same thing.

Hi Kain,

Very strange! What buffer size are you using for processing? Please e-mail us with as much info as possible, possibly a test session with that same test signal, and we'll investigate!

Thanks,
