Re: Boss Super Shifter
For harmonized runs, something with Smart Pitch Shifting would be the best, but those are usually in the more expensive processors. They synthesize a note relative to the note you are playing and choose the minor and major voices based on the key you select. The pitch shifter settings in my Korg transform the actual note coming in to a selected interval. The result is perfect tracking, but you are stuck with one interval, so the harmony will be out of key. This can be dealt with if you are skilled enough to move the rocker pedal to the right point with specific notes, or by setting the interval to 4ths, 5ths, and octaves only.
