[PD] Key-repeat makes keyboard-pianokeys impossible?

[Roman Haefeli]

hi frank

sorry to bother you again with this, but now i am getting very curious
why the quantisation of x-events (from mouse or keyboard) is so big in
my pd on my system and yours is so ok.
 
again, my 'xset q':
auto repeat delay:  500    repeat rate:  30

and pd measures:

print: 512
print: 0
print: 0
print: 0
print: 0
print: 0
print: 85.3333
print: 0
print: 0
print: 0
print: 85.3333
print: 0
print: 0
print: 0
print: 0
print: 0
print: 85.3333
print: 0
print: 0
print: 0
print: 85.3333
 
these values are NOT ok, are they? (512 = 6 * 85.3333)

i am the only one with this problem?

:-)  
yeah, i try to get this precision in pd (i don't intent to divide my
mouse into two parts though)

yeah, man... of course!!! i have this quantization of 85.333ms, when i
hit a [bng] randomly with the mouse. the smallest time i get is also
85.333ms. 

cheers
