Can't really comment on the link, as I've never heard of the site or the product, but I had a DM5, and before selling it I took the opportunity to record almost all the samples from it in case I ever wanted to use them. I got all the kicks and snares I think, and more than likely all the toms, but I skimped on some of the weird effects, percussion and cymbals that I was pretty sure I'd never use in a million years. I have yet to slice them all up into individual samples though. That is a task I don't look forward to.
Why am I mentioning this? Fuck if I know.
