Re: square waves

[Daryl Shawn <highhorse@mhorse.com>]

On the old David Torn instructional video, he mentions the oscillator in 
the machine and demonstrates its effect with some harmonized delays. 
Forgive my ignorance, but is an LFO present as a controller for any sort 
of time-based modulation, i.e., the rate control on a simple chorus 
pedal? Does every harmonizer have an LFO? And do looping machines such 
as the Repeater which offer some pitch control also have an LFO?  Or is 
the PCM-42 unique in having this effect available in its delays/loops...?
