With Yamaha S30, is it possible to simultaneously use a pedal for sustain and a pedal for switching to the next voice? I tried connecting a pedal to the foot switch jack and assigned it to switch to the next voice. I also connected a pedal to the foot controller jack and assigned it to sustain. The voice switching pedal worked fine, but the other one didn't do anything. No sustain. However, for some reason, sustain works if I assign it to both pedals. Can anyone help? I need to use a sustain pedal and somehow also switch voices with another pedal. Tuomas
