Hi Richard, Do enjoy this page on reaction times. If I am reading it correctly it takes 200 milliseconds to modify an already "triggered" synaptic event. "Research findings indicate (Rossetti and Pisella, 2003) that once a simple movement is triggered, the intention to stop the action cannot block its expression. The subjects are able to stop an ongoing action but only with reaction times above 200 ms. It seems that the blocking of an ongoing movement requires an intentional or conscious interference." Clearly voluntary control is too slow for "feed back" from the key to the brain of the player to be of much use. It would appear that consistancy of the touch of an action within the parameters of "not too heavy", and "not too free" is the most important factor. http://www.du.ahk.nl/mijnsite/papers/reactiontime.htm Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T. mailto:pianotuna@accesscomm.ca http://us.geocities.com/drpt1948/ 3004 Grant Rd.
