Hopefully...you guys are not editing your arranger keyboards, using studio monitors...and then use another sound system to perform

Always edit your keyboard using the sound system that will be used to perform..

Studio montors are used to hear detail and most natural "flat" sound.....Example mixing for a CD (users would still need to eq the media for their taste)...

Performers...you will be very unhappy with results if you set up your keyboard using studio monitors or headphones..
