As we speak I am setting up my complete rig in the house and testing the Harmony M for testing...more l8tr on that....
But reading these reviews so far to indicate that for different styles of playing eg: full keyboard mode versus triads, one finger etc, etc, ...would definitly give different experiences for each, now link that to playing level, timing in chord changes, and vocal singing style can ALL effect the way the Vocalizer works......& lets remember all gear has its limits & sometimes work-arounds are required & bottom line if someone is not happy or comfortable with a unit just move on return and try something else. All I can say at this early point is Build quality is excellent & it seems to have enough features for my needs in VH at this point...I will chime in later today after I play it for a while.
