Alright... I posted a while ago about aftertouch on my BS2 and how I think it might be broken... I'm a bassist and honestly synths still baffle me, and I barely understand anything about midi, so please be kind and ELI5...

​

Basically my question is, if I am plugged into mainstage and using the BS2 as the controller, if aftertouch worked would I see it change on the midi display to whatever number? And if it should do that but isn't, is my aftertouch broken?
