[sdiy] SEM VCF Mod

[prototek]

    I want to bring out the "VCF Mod In" on my SEM so I can do S&H type
stuff with the filter. I'm just confused on one bit. In the back of the
manual it lists three different VCF options on that Molex. They are:

Control Voltage Input #1-VCF
Control Voltage Input #2-VCF
External Modulation Input-VCF

    I'm assuming I'd want to bring out the third one listed? Are the first
two for precise 1/V Oct stuff? I just wan to be sure before going in there.

    regards,
    John
