Thank you for addressing the inquiry Noel.
FWIW, I think that SONAR drum mapping is a very powerful feature and the Drum Map manager is a great tool for when you have set up a custom patch.
I've seen it mentioned many times that it is unfortunate that Drum Maps are referred to as "Drum Maps" as they can be very useful for many combinations of synths or samplers. The usefulness extends far beyond just mapping for drums.
I hope that Cakewalk will consider the idea of making batch processes a possibility in the future.
Thanks.
