Correct, and use the SHAPE of the '310 on PULSE.

The "pitch" and "timbre" depends on which VCO is faster (higher frequency). That is the dominant
VCO.

You want a '440. The key here is to have the CV of the VCO being dominant in the VCF as well, and
carefully adjusting the VCF FREQ and FM to cause the VCF to "track" the VCO. Also, this effect
will be more audible for saw and Pulse waveforms. You need to set the ADSR into the VCF to be in
the Sustain portion when you want to hear the effect, and the 'tracking' will be the Sustain
voltage attenuated by the FM pot.
