vlf slow motion

Yes. It is easy.
You need to replace TL074 with TLE2074, and increase series capacitors in inverting branches to 10x their current value. Use bipolar elcos.
Don't try capacitors if you didn't replace TL074 first, or you'll end up with a chatterbox.

This way you have almost static behaviour with discrimination.
