Does anyone know how to get rid of the "loop" sound on the strings in the KN7000? One would think that by the time the KN7000 came out the company would have solved this irritating sound. What I don't understand is that sounds like the piano and horns don't have this loop sound. You hold down a key of a piano note and it fades out evenly. It happens on several sounds of having this loop. The applause and laugh tracks for example--you can hear them start and stop and start again by holding down the key. It is most irritating when you want to sustain a unison string sound.
