Hi,
I have been used Werkstatt without much mod, but recently I did LPF / HPF switch mod.
I cut jumper between VCF and VCA and insert the simple circuit below.
This turns VCF as LPF(by default) or HPF. This has some DC in output and it’s not perfect, but basically it works. I can do VCF modulation in both modes.

Please let me know if you guys are interested with the mod. I will upload sound sample if needed.
