In your audiolab plugin suite, there are a lot of nice filter implentations mostly in moog-ladder style. In case your are interested in implentation of an Oberheim-style filter:

Did someone compiled Pure Data for Apple ARM M1 already?
Best Regards

Wow! Great additions!

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!
