Metro Modular Boethian Wheel - Model 660 - first patch experiments

I had a chance to catch up with Justin of Metro Modular on the weekend.
He explained to me a bit about the 660 module.

There are two inputs at the base ... the Banana is CV. Tiny is audio.
At the top of the module we have the outs -- also audio & CV ( The red bananas are gate outs).

In the centre we have the wheel composed of 32 LEDs.... 8 in each quarter.

The theory is that if you put in two audio sine waves that are 90 degrees apart, like say the individual pole outs on a self oscillating VCF the MM660 will generate square waves at 1x, 2x, 4x, 8x, 16x, and 32x the frequency.
These are available as gate & audio outs.
They are also summed to give a arp like effect (similar to the korg Poly-61 like sawtooth/staircase ARP).

You of course don't need to use just sine waves inputs and both inputs don't need to be in phase with each other. This is where things get interesting.

I did a quick patch using a 281r,292r, 266r, a wogglebug and a CV processor.
I didn't have an audio source so we just used the CV inputs. This was interesting as the 660 became a sound generator.

I've fed the audio outs of the 660 into the 292r - low pass gate.
I'm just using the 292r as a VC mixer

So in this patch the only sounds are from the MM660.
There is no other audio source like a VCO. The MM660's LEDs are triggered using the outputs
of two channels of the 281r function generator which are in self cycling mode. I'm just playing with the 281's envelope's attack & decay.

The wogglebug and 266r are providing CVs to simply open and close the 292 VCAs

The spinning of the LEDs indicates the relationship between the two CV inputs.

Changes in their phase or shape will move the LEDs.
At LFO speed, very little audio is generated, but at higher rates we have sound.
