Are you using a Roland SH-101 (which isn't a module) or an MOTM-101??  The
"random" setting on a SH-101 is a quantized voltage -- it's not that random.

You can patch an output of the 320 into the FM input of the 300 -- sine
might be a good choice.

The 320 also has a saw output, and a reset feature.  You may patch the saw
ouput back into the 320's FM input, so as it "warms up" the "drifting"
settles down, or you could also use a 110 to control the 300 modulation
depth.
