Is it possible to connect 2 USB webcams at the same time? I'm using a Macbook pro, the system does recognize both webcams and when running other video software such as VPT (video projection tool) it works as well. Through PD only one cam is registered in on the device list.

hi all,
I'm trying to get a midi instrument to change its pitch (in real-time) according to the pixel brightness from a live webcam. does anyone know how it can be done?
