Virtual Void SetSurfaceSolo doesn't get called when reaper track is soloed
SetSurfaceSolo doesn't get called when reaper track is soloed

It seems the virtual void SetSurfaceSolo is ONLY called when you solo a track using the GUI/mouse. When you use an action, a midi CC, or Csurf_OnSoloChange gets called, SetSurfaceSolo is NEVER called.

SetSurfaceMute seems to work fine in this regard i.e. as soon as i mute a channel (through e.g calling CSurf_OnMuteChange) then reaper calls SetSurfaceMute. The funny thing is that it also calls SetSurfaceSolo, which in my opinion isnt necessary.

I need this to built proper csurf code.

I think I have something similar going on with IReaperControlSurface::OnTrackSelection(). It is called by UI/mouse selection and IReaperControlSurface::CSurf_OnTrackSelection() but not by actions/shortkeys or Main_OnCommand(). Maybe more IReaperControlSurface::CSurf_On*() methods have this problem, I shall investigate.

BTW should we report dev related stuff in this forum or in the dev forum?

Maybe I am not using the API in the appropriate way. When i press a button on the surface, I call : CSurf_OnSoloChange in order to change the solo state within reaper. That seems to work fine i.e the solo indicator i reaper is lit. With mute/select/rec-arm, reaper immediately then calls the appropriate virtual void (SetSurfaceMute/...), except with Solo, then it refuses to call SetSurfaceSolo

I never used CSurf_SetSurfaceSolo (or CSurf_SetSurfaceMute...) in my code. What is actually the reason for this call ? I always thought that the CSurf_OnXXXXChange was from surface to reaper, and from reaper to surface was handled with the SetSurfaceXXXX virtual voids. Maybe i am missing a step.

I guess as now we're discussing, perhaps we should move this back to the dev forum :-|

Not a bug: apparently you always need to call CSurf_OnXXXChange through CSurf_SetSurfaceXXX e.g CSurf_SetSurfaceSolo(tr, CSurf_OnSoloChange(tr,i), NULL);

I confirm for TrackSelect too: not a bug

This seems to suggest a bug in OnSurfaceSolo, or somewhere downstream from there, in triggering the callback function.

The other functions I've investigated so far -- SetSurfaceRecArm, SetSurfaceMute, SetSurfaceSelect, and SetPlayState behave as as expected, only Solo shows this behavior, and there is no need to "wrapper" them as suggested in the quote.

i'm fine with re-opening this bug, but it does seem that geoff's observation is different than the description i used at the time.

Closing this issue as "Live with it":
- as yhertogh said, the original report wasn't a bug,
- and, to clarify Geoff Waddington's 2nd "issue", when IReaperControlSurface::SetSurfaceSolo is called with the master track as 1st param, your CSurf code must either ignore it, or interpret it as "any solo" (e.g. w/ MCU type of controllers, you have a light that signifies that something is soloed). Also, there is no bug here, because SetSurfaceSolo is properly called for a solo'ed track, and then, there's that other "any solo" call with the master track.

Note: claryfing this issue because I was fooled by it in SWS too... using the master track to notify "any solo" is questionable but since some existing csurf rely on this, we'll have to stick with it...
