If you have two free VCAs, a triangle LFO and an inverter you can patch a crossfade between two of the waveforms.
Send each waveform into one of the VCAs, and the outputs of the VCAs into your mixer.
Send the triangle LFO (sine will also work, but I prefer triangle) into the CV input for one of the VCAs. Now, invert the LFO signal and send that to the CV of the other VCA. The speed of your LFO will be the rate of modulation between the two waveforms, so a VCLFO will give you another dimension of modulation in your patch.
You can use a switch like the MOTM-700 but more often you may want something that smoothly transitions between two or more waveforms. Try using a mixer. Also consider voltage controlled panners. Off the top of my the Modcan 69B Scanner is one of the coolest and most elaborate panners (I love mine) but there are others.

Hi all,
Using the MOTM 300 VCO, how would I go about modulating between the different waveform outputs?
I don't have the MOTM 700 but is that what it essentially does? switch in and out between two (or more?) inputs using any CV? Are there other ways?
Yeah, I'm looking for something that can crossfade, not just switch. That Modcan does look pretty awesome and I see now there are quite a lot of modules out there that do this. Someone else also suggested this much simpler diy crossfade/panner:
