I have got an Elgato Streamdeck. I use the MIDI plugin and insert a 159 bit sysex program, or larger bank file to the Prophet thru the daw and loop midi (and in my situation, network midi). This is great. I am using Advance Scene Switcher to make the videos, with several cameras. Everything is not exact but I am playing the drums to play the prophet. It will be complete soon I just came here today to get the MIDI Implementation chart again, then discovered also the new firmware 2.0.4 from Last year September. But I couldn't resist stopping by the forum to talk to all the other prophet lovers. Here is a link to my video from yesterday's drum practice in which I made 27 new Prophet programs over 2 hours:
