Hi,
I don't have One or other MCU like device... and it seems like after all mods this preset no longer mirror device displays on build-in (on screen) display. So it is hard for me to
follow what is going on there.
"default" text is sent by fader/pot value/name monitors. Temporary text is displayed directly and trigger delayed timer (2sec) to reset all strip monitors (calling _DispUpdate).
Options/Export (Text preset) can help to understand from where particular updates are called.
Note that this preset is for Mackie mode of One. And if you plan serious changes in default functionality that is not optimal. One has "MIDI Relative" mode, where all controls
can what they are, f.e. there is just one display to set, one fader to process, etc. I mean the preset for that mode can be way more transparent and easier to work with.
Hop/jump when switching channels can be from Mackie emulation. One tries to be 8 strip controller, so it changes "internal" strip with some logic. Probably that comes in clash
with "focused" strip selection, I mean the timing of internal channel switch and preset monitoring is bad. Other possible problem is value translation, Mackie devices have
10bit faders, One has 7bit fader. That is impossible to dig for me without having the device on the table.
"MIDI Relative" mode can eliminate internal channel switching and value translation.
