Tom: it is not possible to use the PLG150-DR with the onboard styles of the 9000 Pro. I've tried many tricks that all failed, and Yamaha specifically told me that the styles would not work with the DR - only with midi files.

I love the sounds of the DR but modifying each of my midi files with the SysEx needed to assign MIDI channel 10 to the DR and select the proper drumkit, plus edit the drum sounds and remix the arrangements, is a serious pain that I'd like to avoid. I'm debating whether it's worth the effort to modify and remix hundreds of my live files that I use or if I just want to stick the DR into a new Motif ES 8 I'm getting at the end of this month and just use it exclusively in the studio. Since I'm dreading reworking my midis, the latter option looks good at this stage.
