Use that with JH's OB8 mod technique -- analog switch ICs, using the noise
bit for switching (if you want), etc.
VCO3 reported that it works but the signals were overloading the switch
chip; I think he was using a 4066. One of the DG switches (Maxim?) should be
able to handle it, though. This is a synth-DIY topic, now.
