Hello,<br /> I am rebuilding my Arp 4034 filter and came across your modified schematic. I was wondering why you removed R28 and connected C3 to ground? What effect does this have on the filter?<br /> Thank You.

Hi, as far as I know the modified schematic represents the earlier revision of the 4034 filter. I believe R28 was added and C3 reconnected in later versions in order to avoid transient currents at power up/down. As you may know, the +/-15V supplies typically fluctuate heavily for a short while when switching the synth on or off.

Hello. The 4019 files repeat the 4015 ones.

Your files for the 4019 VCA are wrong. They are all the previous 4015 S&H files
