0-127 is supposed to represent the entire dynamic range from no sound at all to the roar of a airplane, but there are many, many fine dB values between, say MIDI Velocity=60 and 61 that the average listener can easily pick out.

That's why I suggested NRPN with a range of 0-16383 instead of CC with 0-127. Even so, straight up CC has been shown to go far enough to work musically and should not be ruled out. Of course you'll not get a lot of bandwidth width MIDI, but surely enough to adequately control a drum model.

Drumming with brushes vs. sticks would be indistinguishable to the PCM engine, I suspect. Your solution does not address the brush problem.

There is no separate brush problem that I know of, just the sensor data stream.

You have a Roland VG-99 or similar product right?

Yes, I have and know about the difference between the resynthesis and MIDI. I would think a datastream to control a drum algorithm could land somewhere in between the expressiveness of full on resynthesis and MIDI note data.

Anyway, I accept that the Wavedrum is designed as a stand alone audio-only instrument and that control by MIDI would have lower bandwidth and resolution than it would internally.

This sounds like a good solution. Sorry I didn't get it earlier. Embarassed

A lot real drummers (I am not one) would consider the lack of response to brushes on most MIDI drum controllers to be a very real problem that needs to be solved. For them, it would be frustrating to drag a brush over the drum head and not produce any MIDI data, because no commerically produced MIDI drum controller is capable of interpreting this playing technique in terms of MIDI. The usual workaround is to trigger brush samples, but it is a poor substitute.

Even though I am not a real drummer, the ability to use brushes and other implements on a WDX is quite the attracting. So to me, the brush problem is a very real one.

Here is an example of the subtle use of brushes on a drum that no maker of MIDI drum controllers has succeeded in implementing - the brushing starts around 0:51:
