For reference, I hacked a workaround which solves things for now:

; globally:

gktouchused init 0

; in the instrument:

	kTouch aftouch 0, 1	
	if kTouch < 0.5 then
	 gktouchused = 1
	endif
	if gktouchused == 0 then
	 kTouch = 0
	endif

-- so kTouch is forced to zero until the first aftertouch message
arrives.
