I think JSON would be a nice to have feature. But the question is if vcontrol is the right software for this, because listen to an event channel could cause in a vcontrol Crash.
I have tried to read out the incoming xml channel from the e2, because a college have done this with widget Designer. The result is, that if you recall a preset for example, you could filter the xml and would get the data, BUT for a preset recall the e2 sends ~4 Sheets of plain text to the Port. So v-control freezes/crashes instantlY after executing the preset recall… it couldn‘t handle this much Text in a Short Time on the incomming Port…
I would recommend to expand the incomming buffer a lot!
