When in software editor all sounds get an unwanted phasing effect. What is going on?
In the setup midi devices dialog of the editor software you have selected the MC-808 also on “Through – Input” and “Through Output”. Now every note will be send from the MC-808 midi out to the MC-808 midi in again. Every note will sound twice, resulting in the phasing effect. Remove the MC-808 from the “Through Input” combo box and the effect will vanish.
