In addition to voltage-controlled panning, how about these ideas: ---Four VCOs being slightly frequency modulated by a quadrature oscillator to provide a lush 'ensemble' sound. Unlike standard vibrato with a single LFO, or even with four independent ones, the VCOs would be held at a constant, precise detune level (perhaps controllable by Mod Wheel). ---Same as above, but controlling pulse width. ---How about a sine from a Quad LFO controlling pitch while it's 90-degree shifted variant controls pulse width? The harmonic spectrum of the pulse would change, but be realted to, the oscillator's position in its detune swing; i.e., it would be 'Square' at its exact pitch, but have a more squeezed duty cycle as the vibrato pushes to either (+/-) extreme. ---Use quadrature outputs from a VC-LFO to control the switching of one or more MOTM-700 Router modules. Could be fun! Just daydreaming. ---Ken
