Hm, I don't have the kbdrate command on my machine, but alternatively
you may use "xset" to set keyboard specifics. "xset -r" will switch
off autorepeat altogether, "xset r" will switch it back on.

Attached is another way to get at keyboard data in Pd that is suited
to be used to built a midi-keyboard from a standard PC keyboard. It
involves an abstraction "keytrans.pd" which should be used with two
argument as [keytrans <keyname> <midi note>] and will output a list of
"<frequency> <keypress state as 0 or 1>" if the respective key passed
as <keyname> is pressed or released. It's a good example for when
an abstraction can save a lot of typing and connecting work.

Ciao
