Wow - I can't remember what kb I used or even WHEN that party was! If I had to guess, it might be the psr3000, but I'm not sure. As for pedals - I use 2 always and they are both side by side at my right foot. Sustain and vocal harmony ... I have to balance on left leg alot, but I haven't started leaning when I walk yet! LOL
Since playing with the Nord, I may go back to my original pedal setup which was 2 switches and an expression. The organ is so much better with it.
So, that would have (from left to right) sustain, vocals, volume. They all sort of rest up against the bottom right leg of my kb stand and never stray. Heck, I'm standing on the sustain almost all night - they never have a chance to move!
