Feature Request: X-Touch and X-Touch Extender display color support

[RattlesnakeLodge]

Greetings!

Is it possible to provide color display support for the X-Touch and X-Touch Extenders?

CSI has recently implemented something similar, using its new feedback processor FB_XTouchDisplayUpper (https://github.com/GeoffAWaddington/CSIWiki/wiki/Feedback-Processors#fb_xtouchdisplayupper).

Please let me know if you require additional information, reference of similar code, etc. Thank you so much, in advance! :-)

Sure, I could add that, should be a no-brainer as soon as I know which sys-ex needs to be sent. Any chance you can point me to the X-Touch color display MIDI spec or something similar (e.g. code) that lets me know about the sys-ex?

Sent a PM via Reaper forum.

A few more notes...

I think the sysex is the same for both X-Touch and the X-Touch extender, unlike the standard displays for generic MCU and MCU XT devices. So, no need to differentiate between the main or extender units.

Also, it looks like this sysex is solely for controlling the colors on the displays, and not the actual text feedback. The text itself would still be handled by your MCU and MCU XT feedback controller types.

Hope that helps! Thanks again, sir!

I implemented it based on the info in this forum post. The sys-ex is slightly different when using an extender, so I added 2 new display types "X-Touch Mackie LCD" and "X-Touch Mackie LCD XT". The X-Touch must be in MCU mode, so it's essentially a drop-in replacement for "Mackie LCD" and "Mackie LCD XT". Colors can be picked - as usual - with the 3-dot button next to the text feedback field.

This doesn't work on the X-Touch One. The color of its display can also be changed, but apparently only in MIDI mode. In that case, it's the same (or almost the same, not sure) sys-ex as the one which the X-Touch would take in MIDI mode. I haven't implemented LCD / color LCD support for MIDI mode because it suffers from lack of 14-bit faders and therefore I don't recommend it anyway.

For the record: It took more effort than I expected because of the fact that you can't simply tell the X-Touch "Change color of display 5 to red". Instead, you always need to send the colors for all displays of one unit/extender at once. This needs global state scoped to the MIDI output device. Good thing: Now it's implemented cleanly via FeedbackCollector and RealearnSourceState and we can use the same structures in the future for similar cases.

You rock, sir!
