Hi All,

I'm enjoying the new quad vclfo. However, when I use it at
audio rate, it sounds like there is some 50Hz modulating the
vco - so the wave sounds quite raw. Its similar to the sound
you get when you plug a cable into a cv of a vco, and then touch the hot
pin, so as to feed some 50Hz hum into the circuit.

Does anybody else notice this too, its particularly clear in the few khz range

I've moved the unit to a different rack, and also checked if this
modulation disappears when you make sure all inputs are connected -
to no avail. In comparison, the waveforms on my 143-3 sound clean.
