[sdiy] 10 VPP VCO in 3VPP max VCF

[ganesha]

Hi,

I would like to build the Korg MS50 VCF as a module in my synthesizers.com system.
But the dotcom VCO's are 10VPP while the Korg MS50 VCF has written 'Max 3VPP' above the input.
Is there a way to convert the VCF to 10VPP? Would an extra input buffer (that divides the input by3) and an output buffer (which multiplies it back with 3) be a sollution? 

Thanks,
Kris.
