Sorry I don't have a complete list. I mainly use the O2with the XO. I agree with you about some of the problems with Trigger Finger.

This is good to know, Rick.

Cross the roll-up keyboard off the list.

I've the Trigger Finger as well (actually, I've got *very many* control surfaces). Well built, portable, relatively impervious to dust and dirt. One drawback (no doubt shared by many units): those four *slider* knobs come off *very easily*. Interestingly, the 8 *pot* knobs are very snug.

Unfortunately for my needs, 8 pots and 4 sliders; I come up 4 short (I need 16).

A comment regarding the Trigger Finger (drum) pads: I find pads a poor substitute as triggers for both buttons and keys. Both of the latter trigger reliably; a light touch on a pad may or may not. And pads sometimes double-hit. In addition, I find the velocity sensitivity of pads pretty useless; keys are better. Neither give the level of sensitivity I usually find useful, however.

If I needed to use a pad in connection with amplitude info, I'd use a slider (or pot) to specify amplitude and just use the pad as a trigger. (One of my versions of "What's in a Name?" does just that.)

Rick, any further suggestions? As a matter of fact, would you maybe have a list of MIDI controllers (USB) that work with XO?

M-Audio Trigger Finger works with XO
The roll up USB (which I own) does not

Thanks, folks, for the recommendations.

David, this would seem excellent when MIDI notes were required. I  wonder whether these rolled-up keyboard are "plug and play (notes)"  or whether they require software to be installed?

Such a keyboard nicely addresses portability plus "keeping the dust/ dirt out." Crucial. I expect that all other MIDI keyboards would  have a problem with dirt/dust.

Actually, I've solved the keyboard problem by using the (OLPC) ASCII keyboard with sensekey. That works well. (I don't need notes, just on/off buttons.)

What I'm really looking for is a 16-pot or slider control surface.  Does anyone know of a unit that would be impervious to dust/dirt in  problem environments? (I can't think of any.)

I note how much more expensive MIDI foot controllers seem to be than table-top control surfaces. I presume most of the cost is in rugged construction, keeping dependability high (given rough treatment) and dust/dirt low.

Why don't you try something like this:

You can just roll it up and take it with you and the OLPC.
