How about buttons that actually 'CHANGE COLOR' when activated (pressed), to display its operational status, as the Tyros arranger buttons do? Initially I initially thought the Tyros' color changing 'lighted buttons' were added merely for flash and glitz, but this feature is actually VERY useful for LIVE performance navigation.

This leads to another idea re buttons on the Ketron arrangers. How about Ketron offering buttons which also come in various FLOURESCENT COLORS which GLOW in the dark, so they would be viewable on a dimly lighted stage?
