It looks like the soundbanks for Rob Lee EDM #2 and #4 contain the most drum patches. I'm pretty sure those are all synthesized instead of sampled.Those people who have all the soundbanks, I really hope you can sift through the drum presets and share the ones that can be used if you don't want to build from scratch.
I own the Everything bundle and have been playing around with the Player to see what limitations it has. It looks like it imported all of the Everything bundle official soundbanks just fine, so if you purchase any of their official soundbanks it should work. Unfortunately it does not let me import any custom presets I made with the full version of Synthmaster.
I think the solution will have to be that those of us with full SM put together some drum patches for the community and then supply them to KV331 who will then be able to encode them into an official soundbank (smpb) specifically for this OSC. Otherwise I really don't know how anyone with the free player will be able to make drum sounds as it only lets you manipulate patches with easy controls instead of customizing them.
