[PD] Attaching a Sensor to Acoustic Instruments Question

[Pedro Lopes]

Tracking in that sense requires you to have gear that is in visible line of
sight to the musician. If its a concert situation maybe that's not easy. But
its a way to go. Note that will not produce good tridimensional tracking
results, one could use a kinect too.

If we want to hyper extrapolate, if the concert is in a controlled room, you
can use 3D IR tracking system, such as used for mocap. Real expensive but
really accurate. :)

Best luck,
Pedro
