I enjoy using this too. With monophonic sounds it's a bit like tapping
on a guitar. :)

Is this a limitation of the keyboard scanning electronics, or a software
thing, I wonder? I have some vague memory that it's possible to change
the baud rate of ps/2 devices too.
There are many good points in your post. I would add some more...
I think it would be interesting to try a layout that does not mimic a
There are twelve keys from 'a' to '#', from 'q' to ']', and '1' to '='
on my keyboard. These could be chromatic notes, with 'a','q',and '1'
being the lowest note of each octave.
This would give three octaves on the keyboard, and I don't think it
would be harder to play.
I had a go at doing this in pd, but got stuck converting the key codes
into midi note numbers.
I think that with the mouse it would be good if there was an option for
the controllers to be activated on left click and reset when the button
was released... as there is no 'null' point on a mouse, it would be hard
to use it as a pitch bend/mod without leaving an offset when you want
both to return to zero.
