This is much more similar to the original Lexicon PCM 42 square wave modulation which plugin I currently use.
Chorus square wave and rate here works to modulate Harmodulator different pitches tuned from -4 to +5 and ! octave up.
Use exp pedal to control Modulatio depth from -5 to +4.
I love to use sqm to improvise because it is nor really a looping stuff.
