I've never really found a satisfactory tape delay in Pd so here's a new thing inspired by vintage tape delay machines. Running on MobMuPlat tested on Android smartphone and iPad mini or, of course, desktop.

Time knob from 50-2800 milliseconds.
Feedback knob can be turned all the way to create a loop.
Drive adds a soft overdrive.
Dry/wet is a mix knob.
Smear moves two of the three playheads to non equal positions so that it creates irregularly spaced echoes and it is subtly different each time you turn it on.
Four presets are built into the top four buttons.
