Problems With Vibrato Effect

I’m working an a c64 style chiptune and there the use of the vibrato effect (0f) is necessary for me.
when I set the vibrato for one note, and play from the notes position on, the vibrato sounds correct. but when i play the pattern from beginning, only the first note sounds correct, and all following notes which use other vibrato parameters sound incorrect.
the thing is, every single note alone sounds correct. only if i play the whole thing from top to bottom, it screws up.
andy ideas what’s wrong ?

edit : this problem only occurs on the instrumtes where the “volume enveloped” is used / turned on. I have no clue whats wrong :unsure:


Sounds like a bug to me. Strip the song on all patterns and instruments but the vibrato error and send it to the Renoise team…
