Behringer 130 Dual VCA required modification information

Someone will watch this video of mine and say “why make this modification, are you using VCA and VCO without a filter?” Maybe he's right... but I'm an idealist! And I cannot turn a blind eye to gross violations in circuits and everything related to sound.
If you are not one of those who will say as I wrote above, then watch my video! :-)
