The manual (at present) really isn’t very clear on what happens to the various controls: Density, Overlap and Window when the Blend knob is turned to the left of centre position. Maybe you could clarify what effect these controls have on the unit when they are turned in the phase vocoder position please.
And, at the same time can someone tell me how exactly the blend control functions between the two states. As you approach the centre, is the other half included in the blend? As an example if you turn the knob from CCW > CW through the centre, are you also getting some of the granular state the closer you are to the centre point, or does that only apply once you pass the centre point?
I hope that’s clear … 
Thanks in advance.
