Panoramix echoes position messages sent into it on the message output. It also outputs positions of manually moved sources. Sometimes one needs to separate these cases.
While there is the idiom [t 1 l 2] → panoramix → gate to detect and reroute output of just sent-in messages, it could be handy to have panoramix output something like /track/1/source/dragging [bool] when a user holds a source with the mouse
Best!
