I dont know if anybody else has thought of this but if like me you are using 2 keyboards on-stage that are not midi'd together! what do you do about pedal sustain for each keyboard ? have two pedals! no there is a simple solution, get a 'one into two' jack splitter, plug the sustain pedal jack into the splitter, plug the splitter into one keyboard and just run a short jack lead from the splitter to your second keyboard, works a treat
The only downside is that some keyboard manufacturers use different pedal command polarities so you may find that when one keyboard sustains your other keyboard will be working in reverse, most recent keyboards have reversible pedal polarity option anyway.
Thats all for now.
