I too am trying to create a sysex slider which changes a multi-byte value. I simply cannot find the screens shown in the linked answer. Can you explain how to get to the Sysex Properties screen for a newb?
I have created a slider, set the message type to sysex, even used the "Learn" function to read in the message. However, I cannot for the life of me find the page called "Sysex Properties". The "Control - MIDI" page looks different than mine too.
I am using version 1.6.5 build 1650.
