Help creating classic 303 Obsidian patch

I’m trying to recreate a classic Acid 303 sound in Obsidian. I know this should be easy, but the resonance on Obsidian doesn’t feel quite the same as other synths I have used. There is a Classic Acid patch in the factory bank, but it doesn’t sound right and I’m struggling to tame it. I’m wondering if anyone has a patch they could share?

    this is very complicated... oscillators and filters in Obsidian are not designed to emulate 303 - it sounds very different.. there are some things you can do but you get never close enough...

    IMy suggestion would be - save your time and use simply Troublemaker AUv3 plugin ;-) That is it, instant 303 sound (and more)

    Dude that's the perfect answer... I just got impatient and bought Troublemaker B) Thanks for confirming I made the right choice! I'm playing with it now, and it's not quite as squeaky as the lovely 303 patch I'm using in Reason, but I could probably EQ it and push a bit more out of it, and it'll do for live. Just exporting a mixdown of a track with the 303 removed so I can play around jamming with the cutoff and resonance and see how it feels. Thanks again man!
