Description
a pt2399 delay which cuts on or off, dependent on the input signal crossing an amplitude threshold. the original memory loss design (2015) was a fairly crude circuit bend. The signal was boosted and split, a highpass signal fed the delay line and a lowpass signal blasted into the ref voltage of the chip. This forced the chip to distort and reset in a rough and glitchy way. I tried cleaner interpretations of the circuit hoping to improve the design but missed the gritty sounds. With this revision i’ve made the control mechanism more robust by using bjt transistors to do the switching. This also allows a few more variations to the distortion/cut off and inversion to the reset behaviour. Wet and dry signals can be mixed independently and the preamp is an attenuverter, having noticeable effects on the distortion character but also very effective for control in external feedback loops
