Here's an example of mono.

There are 2 ways to do this but would be handy to know if its a synth or an effect, basically poly or mono, white or blue?

Perfectly normal behaviour for timing / redraw using green.

Have you checked this behaviour in other DAW's or hosts to see if its FL specific?

This program is not for kids, its a complicated one, if there are buggggsss its your fault not the programs.

Wow forget about sine, just when I'd come up with a new version, oh well here it is anyway.

To get the same shape sine as in the link simply PM/FM the sine with a second sine offset by 90 degrees
you will not be able to get full PW mod before it distorts but you will get as much as is displayed in the link.

Edit added example

If you just want to use it on waveforms pop you wave into your favourite sound editor (try Audacity its free)
hit normalise and jobs done
If you want it in real time there is no way to do it without compression / expansion.

I think what djbrynte is referring to is a kind of splash screen using the gui of the plug with the menu saying something like loading resources, which makes you think the plug has loaded instantly
Or I could be way off base, it has been known

I can't believe anybody even downloaded and tried something that intentionally crashes flowstone
it has enough bugs anyway.
