Nice tool. And like any tool, it certainly will have applications. Then again, it can never cover all applications.
I'm not one of those guys who fears "being replaced by a machine" .... I just saw the Frank Zappa DVD ... Does Humor Belong In Music ... and there was Chad Wackerman playing a hybrid drum kit. Real kick and snare, real cymbals, electric toms. And this was 1984. The e-kit worked for Chad ... and it worked for Zappa ... and that was 27 years ago.
Personally, I love drums. I have 5 acoustic kits ... plus a Yamaha e-kit, and a Roland kit, and a Roland SPD-S, and an old Tama Techstar 305, and two Korg Wavedrums, and two Mandala V1's. It's all good. No fear. I'm 55. And I really don't think any electric kit/or box, is gonna come after me. Not in my lifetime. And after I'm dead ... well, I'm not so worried about what happens after I die. Like, I'll be outta the game. Right? Should I worry about what's gonna happen in 50, 100, or 200 years from now? Hardly. I got stuff to worry about, today, tomorrow, and next week. OK, maybe not so much worry ... but stuff I need to deal with.
What I find, is "Americans", by in large, are not a "progressive" lot. We romance the past. We're stuck "somewhere", whether it be 100, 50, or 25 years ago .... we're not "now". So, don't expect to take away our big cars, guns, and acoustic drums...anytime soon.
Me, I'm to old to become a drum programmer. Just am. Now, if a guy wants a gig with Trent Reznor, he'd better now how to program. On the "other" hand, if you drum in a bluegrass band ... probably an acoustic kit is all you need to master. Apply for the job you can do ... let someone else do the gig you can't do.
I say, "good luck with your machine" ... hope all the best for you. Hopefully, you'll be a millionaire, in two years.
