[sdiy] voltage controlled filter???

[James Patchell]

I can't remember which ones have been mentioned.  Here is the list of parts 
I know of:

LM13700 (National)
NJM13600 (NJM)
NJM13700 (NJM)
NE5517 (On Semiconductor)
CA3280 (Intersil)
SSM2164 (Analog Devices)
and a couple of parts by THAT corporation whose part numbers escape me for 
the moment.

Actually, not too bad a list, but it is shrinking.

Also, you can make a simple OTA using the THAT340 transistor array or the 
CA3096A Intersil transistor array.
