[sdiy] Most simple VC-BPF please...

[jbv]

Bonjour la liste,

I'm presently working on a project requiring a large
amount of independent VC-BPF.
Could someone be kind enough to point me to the most
simple VC-BPF schemo (in terms of parts number and
PCB room), thus offering VC control for Fc and Q ?
What I'm looking for should cover the whole audio range
and allow very high Q for very narrow BP...
What I'm expecting from this request are solutions different
from the CEM chips and the CA3080 based schemos...

BTW, I also need the 1V/oct Fc control, but don't know yet
whether a converter will be included in each BPF, of handled
by a centralized / shared ROM-based converter...

Thanks in advance.

JB
