I stripped off the HP-calculation of the Karlsen filter abstraction and got ca.35% CPU Saving.!
Only used the clipping -1 +1 , no tanh calculation

27% with 8xOS

21% with 8xOS without HP-calc

My PD uses 7% in neutral mode(not running an abstraction)

It would be more elegant to use a switch in the HP pd... but nevertheless for your moog you need only the LP-part of the Karlsen Filter?!

Nice explanation oid. Desired imperfections results in perfection

Hey no problem jaffasplaffa, it was just an observation by me. Happy Christmas

Hey oid, your OSCs sounds so nice "imperfect" ... Imperfect in sense vintage style Thanx!
Seb and Jaffasplaffa, is something wrong with the HP mode? When i use the LP mode i can cut the freqencies of the sound to zero(no sound output). In HP mode it fails?! Is this intended?

Thanx Seb!

you have email

Looks delicious!
Are you usind Bandlimited Oscillators?!

It coexists well in my Automatonism Fork

First of all thank you so much for your filter, Jaffasplaffa. I have tried it, but with 4x Oversampling it gets also super heavy on my 2009 imac :D
I will try to integrate it into automatonism, if its ok for you?!
