Woodman,
Just ordered me an exr-3 (my first keyboard)and being a complete novice please tell me if I'm talking complete nonsense.
As the exr are relative new keyboards it might be hard finding a specific INS. If however you could reuse some work done for another (more-or-less) comparable model you might find some usefull info at:
http://www.lilchips.com/oldsite/cakewalk/ins/index.asp ... please share with us your opinion on the exr-3 (see my previous posting). Up till now I've only seen reviews of exr-5 on this forum.
regards,
Louis
