Well, totally variable delay time is desirable, but being able to switch to
some musically useful ratios, (1/2, 2/3, etc.) would probably be just as
good. This could be a general master control, or perhaps the setting could
be saved per loop?

My experience is that I like to be able to record/overdub at varying
speeds, and later be free to change the playback. Now obviously you
couldn't go back and change rates in an overdubbed loop, but perhaps each
loop "register" could remember it's current setting?

Really what we all probably desire is a "quad" Echoplex with sliders for
mixing, and integeral effects with multiple sends, etcÉ

So if we take the Echoplex, Rolands new SP-808, and Davids "Fly", and put
them in a blender, we come up with something closeÉ
