Good solution. I remember someone way back was working on a library of externals
for sensor data, ways of smoothing the data out, noise-reduction etc.. I Think
it was Johannes Taelman? I've not seen him post in some time now..

Ah Wacom, what wonderful people. I looked into the source-forge project, but its
only for serial tablets! (no longer made) so USB is not supported. There must be
someone working on it though, I'll let you know if I have a proper HID driver
for wacom. I guess I'm just stuck using the tablet in linux then! (I had not had
any luck in the past, but HID sounds like the best and easiest solution!)
| Let me know how it works for you.
I don't think i've outlined the project for you, but basically pixelTANGO is a
replacement of "V_" which was a set of high-level gem abstractions. Well I got
hired by the SAT (in montreal) to make a "video mixer" in PD, so I just made the
mixer an example patch for a set of abstractions that are much more useful than
a mixer! Anyhow I have memento state-saving working fine, including simple
animation of these paramters. Each abstraction will have a automatically set OSC
name (like /pt/1/pt.fader/1/r for the Red value of the first instance of
pt.fader in layer #1. What I want is to create a dynamic patch that allows you
to map any MIDI controller (or perhaps even HID variable in the future..) to any
parameter. (via menu rather than via manual patching) I'm thinking auto-ranging
would make this a lot easier, since I would not have to worry about scaling the
values of each controller! (or HID device, or A2D value from AID)
Ok back to work!
