Hello,
I'm getting stuttering data output from my wacom tablet using the latest HID.
stuttering .... I put a [timer] on the output of the abs X position messages, and discovered that the HID object spits out around 4 X position messages in one go ..... i.e. without any time delay.
I've got a patch where you can really hear this (it is using a vd~ to do a dopler effect on ambisonic spatialisation stuff).... if I do a straight consistent line on my Wacom, the output comes out all stuttery and spitty.... and I have traced the reason to the fact that (around) 4 messages get spat out at once. NOTE: changeing the poll value of the HID object does not aleviate the problem.
I concluded that this is what the timestamp (inlcuded in the USB messages) is for.... right? .......... the USB driver _or_ the USB device( I dont know about these things) instantaneously spits out 4 X positions and includes the timestamp between them.... so it should be (by using those timestamps) possible to get PureData to space out those 4 messages in time and hence get a smooth data line.
do I sound like I dont know what I am talking about? does anyone want to educate me?
