Any feedback possible from opening midi editor?

[joeyxsam]

I'd like to be able to open the midi editor in reaper and have that send a message to touchosc. The purpose of the message would be to automatically change the page on a pager device. I.e. Page 1 has buttons related to arrange view, page 2 has buttons related to MIDI editor, automatically changing these pages depending on focused context of arrange vs midi editor would be cool. If possible, what target would I be looking for in realearn to make this happen?

I can't think of any way to do this with existing targets.
