You make a lot of interesting points, but here is my perspective, and it's a perspective that might be getting overlooked. You call this stuff a transitional technology and I'm thinking more in line with... Wow I remember five years ago when guys were calling the Drumometer that parking meter thingamajigger that's not as good as my $5 metronome, that I swear I'm not using to count exercises incorrectly. So first maybe congratulations are in order for moving up the public acceptance food chain by leaps and bounds.I see both pieces of electronic kit here as transition technologies. What I mean by that is that I suspect both will be superseded in the near to middle future by something that does the same thing only better as well as doing so much more. What you and Bob have done I think is point the way to possible applications and developments.
What I find genuinely surprising is that the full potential of electronic drums has yet to be exploited and I suspect this is because we (the drumming community) are thinking too conventionally about electronic instruments. We are too set on thinking what they can't do rather than what they might be able to do.
Counting strokes can have some utility and is difficult to do with acoustic drums (carbon paper - stop watches all that kind of thing) but as some have already pointed out it is of limited interest. But an eKit that could show you graphically exactly where your strokes fell set against a quantitized reference point - now that would be something that could be used to practise and develop a whole range of drumming skills (not just speed and endurance). I suspect the technology to do that kind of thing is already here or very nearly here.
But I am a little surprised by how few see the value in playing dead on to a time marking when so few even get close to doing that well. They say Well I can practice to my metronome clicker, then they go right back to making the same mistakes they made when they told everyone they were playing at 250 for a full minute, when it was a lot closer to 150. Then they went to the session or rehearsal and couldn't understand why everybody was so angry.
Let's also understand that there are a flood of high school band directors who would love the luxury of a dead on drumline every time they head out for Saturday competitions, to say nothing of classical percussionists and cruise ship drummers who better play the dance instructor's tempo exactly or else. I've also found the integration of a synchronized dancer to music highly musical...meaning that our overused musicality word may have a great many definitions besides the ones we hold close.
I know my head is a little more invested in this than everyone here...and don't think I don't appreciate the input...but I'm seeing this as demonstrating the wonderful flexibilities of both technologies, alongside the first step to something else entirely...where the Drumometer demonstrates its flexibility to do any number of things in a practice situation before a drummer goes out in the world to make real music. This presentation is as much about showing that the thought process on this stuff has evolved enough to begin moving towards this and many of those things you guys have mentioned here. But regardless the configuration as it stands is to me pretty cool.
