Hi Art, There's also vkeybd on linux and I'm sure has to be something on OSX. Just some background information: the virtual keyboard is pretty easy to use and at least for me will serve a purpose for testing and on the go work. It's not very big code-wise so shouldn't add much to the distribution, and might be nice to have as an option everyone can use regardless of platform. It's also completely encapsulated (at the moment) in a plugin library, so can be ignored and stripped out if desired. It currently has all 88 piano keys showing (something which I would have liked in vkeybd). I think controllers and all would be nice to have as well, though only useful really if the keyboard input (the typing keyboard type keyboard) works so one can type and use the mouse at the same time to do controller signals. I'm getting a bit frustrated at the moment trying to get this to behave more reliably, but I imagine it'll be possible. When that's finished, I was thinking a couple FLTK roller widgets for pitch bend and modulation, then configurable sliders for other things perhaps. It would make developing MIDI instruments on the go a little easier, and other situations where you just want to test out a MIDI instrument but don't want to get everything setup. Anyways, just some information. I'm sure it'll be nice to get your feedback on it, but I think it will be better to get a first solid working version done, have it out to actually try and play with, then get feedback for further developments based on real usage.
