MIDI translator help

I'm using J-ORGAN for playing virtual organ and now i'm finding very difficulty to switch organ stops during my live performance with the mouse and my connected MIDI keyboard sends sy exc on/off messages and now i wan't to use this incoming sys exc messages to switch on/off organ stops just like what i'm doing with the mouse.
Now i don't know what MIDI message it requires when i click something on the monitor,and how can i switch organ stops without using the mouse and how can i know the appropriate MIDI message that is needed to do the same switching operation of the mouse?
Waiting for the help.

Thanks,
sunny

Hi Sunny,

I don't know J-ORGAN myself. As you know, you can use MT to send arbitrary MIDI messages and keystrokes to J-ORGAN in response to arbitrary MIDI messages received by your MIDI keyboard.

Now, if J-ORGAN supports MIDI messages or keystrokes (e.g. keyboard shortcuts) as input method for switching organ stops, MT should help you. You should ask the maker of J-ORGAN if it can be controlled with MIDI messages or keys.
