Bank change command to an external midi sound device

It would be nice to have a midi plug-in that can send a bank change command to an external midi sound device.
I thought of it while using an external midi sound device and zynthian together.
It seems like a necessary feature.

Good idea. Feature requests go here: Issues · zynthian/zynthian-issue-tracking · GitHub

                  lv2:symbol "MIDI_OUT";
                  lv2:name "MIDI Out";

you manually compose the message so you need to know what the bank change status byte is for the external device (it’s not part of the midi spec, vendor specific), but you can do it.
