The SDelay can be quite a powerful tool when automating, yes automating, the delay times and increasing them over time having the feedback at a very high percentage (99%). The Input then can also be turned off completely. By changing the rate the times increase/decrease fascinating tunes can be created.
However the times only go up to 2s. 15s would be good 60s would be better but never enough. I realized most Djs and producers with AM are not aware of that great future, so developing the SDelay for improving the automation and whatever would go with that would be a milestone in AM. I think Ross Bencina should just try it out himself lol.
I use that SDelay in almost every track I make, and there would be no AM for me without it (I would probably just fall in a depression) so please, try it, and improve it.
