Anyone have ideas how to make a very nice feedback control for delays? Perhaps coupling it with nice saturation to prevent the signal from overloading. Any tips are welcome.

Don't know if you were looking for something cleverer than this but I would do something like this example:

Just stick in a one-tap delay, and add the output of the delay back into the input. You can stick any effects module you want between the output and the input, and further effects if you want them before adding the delay to the dry signal.

Does that make any sense?

Sorry, I realise I could have arranged the modules so that you can see the wires more easily, but basically it goes something like:

Feed signal into single delay, then through square root, then filter, then add back into the single delay's input.

Add output of filter back into dry signal.

Oh yeah, it's important to have an amp/mixer module in the feedback loop to stop the signal just getting louder. But you knew that. Very Happy

Thanks. What's the purpose of the square root? It looks like you connected the feedback loop from the pro-52 filter, is that correct?

The square root is just an arbitrary effects module. I just like the sound it makes and the fact the output converges towards +1.

And yes, the filter outputs into the amp/mixer, so is involved in the delay loop.
