I would suggest you look at [delta]<br>the bigger the difference between two consecutive position measurements, the higher the speed of movement (provided that your measurements occur at regular time intervals)<br>gr,<br>Tim<br>

if you need to measure the time between two events, I think [timer] is what you need. the attached patch might work for you- move the slider all the way to the end to trigger and gauge the speed of the movement. slide it back to zero to reset. <br>

Hey all<br><br>I've had an idea, using a joystick to symbolically strike a bell, (I.E. when one axis hits a certain figure the bell sound is triggered, possibly with the timbre varied by the other axis). However, does anyone know of a way I can measure the speed of this movement using pd? Basically, the change in velocity in the half second or so before reaching the 'strike'. <br>
<br>I'm not sure if there's anything in PD to do this, but any ideas would be welcome. <br><br>Cheers, <br><font color="#888888"><br>Andrew<br> </font><div><br><hr>Get a free e-mail account with Hotmail. Sign-up now. <a></a></div>
