Wasp filter Vintage and AE modular

I'm just getting into the AE modular.
The lovely small format is esp useful for live performance.
I can carry a whole modular in a small suitcase.
And its battery powered.

A friend asked me to do a video comparing WASP filters.
I hope this helps the community.

The Tangible Waves / Abused Electronics modular

The WASP filter is based around a simple CMOS chip.
The 4069.... its an inverter.
If you're going to build one the CMOS ic has to be unbuffered  ... use CD4069UB
The original vintage circuit also uses the CA3080 ... a OTA...Operational Transconductance Amplifier

The AE modular wasp inspired filter uses vactrols for controlling the filter frequency.​
