Those are fixed (non-VC) filters. The only things you could
factor out are bypass, input level and perhaps output recovery
gain if any.

So you have N filters but can only use one at a time because
there is only one I/O circuit ? That's all right for a stomp box
but for a synth module, I'd rather be able to use more than one
at a time. Even if that means separate modules for the bypass
and gain/recovery functions.
