I have a new midi controller and tested it with the latest gamma. (2020.1.0) There are some problems with with the ChanelFilter node. The change node isn’t registering observable messages (I changed it with a hold latest and used the on data bang) and the to observable(switch) is also not working properly so I just ditched it altogether.
