Really great podcast Phil. Loved the DIY discussion and the interview.
A bit of a bummer that the DM10 patch load will replace the existing sounds and can not be extended for custom soundsets, but it still delivers on the promise of giving the user flexibility and keeping the sound fresh.
Considering that the factory sounds seem to be a blend of many instruments, kits and styles including electronic and percussions sounds the possibility that you could use the same memory for sounds exclusively targetted at a specific style (or even a single, highly nuanced kit) is very appealing.
