One correction to my previous post: on my synth (obviously a Kronos) the setting to avoid doubled notes is identified as "local control" in the global settings. If the local control is on, the keyboard plays notes entered from the clavier. This will, however, cause doubled notes to be recorded. If it is turned off, the clavier will not sound played notes, but sounds them as it echoes back through Cakewalk. The "cakewalk.ini" file can be edited to turn the local control on or off during startup. I believe the default setting turns local control off, but your system might not be doing this. Hope this helps.
