Phase retriggering issues for the first few seconds, then stabilizes

Hello!

I’d like to point out this issue where a static Phase Start value will still make the attack fluctuate unpleasantly for a few seconds each time you hit play. After a couple of seconds it stabilizes.

This seems to happen only with certain wavetables.

Is there a way I can upload a preset for you to check?

Really hope there’s a way to fix this.

Thank you
