[PD] delay with feedback and clipping

[pix]

dereks solution of using limiter~ is also good. i only just noticed it
myself. i think it's in iemlib by the way. you could tie the power of
the delayed signal to the power of the unprocessed signal, but with a
longer decay time so that you don't clip off all of the effect. there is
information on how to do this in the "modes" help subpatch.
