Roberto Raineri-Seith | controlvoltage.org 904-A VCF clone for Eurorack first (rough) prototype test

"The 904-A is fitted with a single Asys RS-95E VCO pulse wave and of course the prototype is only rough calibrated and assembled with standard components. Alpha pots and selected components will be used in the production version, along with a slightly larger frontplate (14 HP). At least the resonance levels must be further adjusted, so there's a little more job for my engineer... For more infos please go controlvoltage.org"

Update: "Audio signal is provided by a single Asys RS-95E VCO pulse wave.
In this first test the prototype is only rough calibrated and assembled with standard components, Alpha pots and selected components will be used in the production version, along with a slightly larger frontplate (14 HP).

First impressions: the frequency response works as expected, but the resonance levels and response must be further adjusted to match the original, so there's a little more job for my engineer..."
