[sdiy] Multi-Input filters

[Grant Richter]

God Bless the Internet, a SURE source of humility.

It would be interesting to see dates, the "cross-pollination" would be
interesting. Like:

Buchla Lo-Pass Gate (Simple Vactrol Sallen-Key)
Korg Polyphonic Ensemble (Simple Vactrol Sallen Key (peaking?))
Korg MS-20 (OTA Sallen-Key with peaking control LP and HP versions)
Wiard Borg Filter (Vactrol Sallen-Key with peaking control and pannable LP
to HP mode)

In other words, take all the previous designs, layer them on top of one
another and smush them into one big "new" one.

Don't shade your eyes....plagiarize!
