"unmapped regions" warning in instr. editor

[gaucho]

do you ever receive the \"unmapped regions\" warning after using the wizard? how can one avoid this?

I\'m looking for a quick way to assign phrase samples (not pitched) across the keyboard.

I\'ve noticed that message when using a mix of stereo and mono waves. The editor only likes to work with one or the other - not both.
