Any constant signal at input results in zero at output, rising signal will give positive value and falling negative (main output). Input goes through envelope follower which is compared to its own delayed version and difference of two followers is sent to output.

Top knob controls input gain/attenuation. Middle knob adjusts lag time for followers, bottom knob sets time difference between them. Upper three lamps monitor positive output (or Rise), lower three lamps monitor negative output (or rectified Fall).

Out is main output where goes bipolar signal. Rise is output of "attack" phase (positive signal), Fall is output of "release" phase but rectified so it's also positive.

Ok, that makes sense. Thank you very much, I appreciate it.

Initial inspiration comes from inductor element in normal AC electronic circuit – acting/reflecting against change. In practical sense I think the most obvious use might be to place it after envelope follower or envelope generator to get an extra modulation related to and at the same time very different from source. You can also check what it does to LFO or oscillator - keeping in mind that there relation between frequency of source signal, block's delay time and output level.

Could someone please explain what this might be used for? Modulation type stuff? Sorry, I still have a lot to learn about modular
