HI, there is actually a pattern every 8 notes chromatically. Every 8 notes create the same frequency but indeed, it does alway jump back to the same hands off frequency each time. Some patches are louder than others but that makes me thing its got something to do with whatever is engaged in said patch...VCO, VCA, VCF, PW, PWM or any other changeable parameter. When the patch is loud and buzzing 'organ' like, you can't hear any problem but as soon as you try to create a nice mellow pad, its too noisy to use. Especially if you change notes a lot because you end up with the sound of a crazy high pitched circus organ playing in the background.
