Synplant2 producing weird sound during sustained playing. Have a listen to the attached audio. Encountered in Logic Pro and PluginGuru Unify. Please advise. Thanks.

You seem to have forgotten the attachment?

Can you please attach the .synplant patch too?

I used .wav file extracted from a soundfont.

Here you go.

That's going to be the modulation envelope I reckon.

Haha that Inst 1_bip was pretty hilarious.

Now I want to make a track where I use that sample and play sweet 80s horn stab chords.

And if I hold any notes too long you get that wonky signal instead of brass.

But seriously it sounds like something in your patch is getting modulated, no idea what.

It''s actually difficult to understand what's inside a Synplant patch without understanding the sound engine, and for some reason that's slippery even if you go into the 'DNA' section.

There's a lot of modulation of obscurce paramaters that gives you that weird, infinitely detailed wonk.

Maybe FM modulation?
You can go to DMA oscillator section and put fm_mod to 0.5 and adjust fm_amt till it sounds good.
