MFB Sequencer weirdness.

Here are my MFB SEQ-02's. Very nice compact step/pattern sequencer. More geared towards musical scales than controlling rhythms like their SEQ-01 I think. These gave me some real headaches however. MFB, Muffwiggler forum, and the SDIY email list solved it for me. I was plagued with a high level, high frequency ripple. About 2 volts P-P, and 400 kHz. The picture below shows the noise. Turns out the shield from my patch cables was putting a capacitive load on the CV output and was causing all the problem.
