midi track mute automation

i found out something wile trying again to automate the midi  MUTE on and off (for live playback to switch to other instrument), and it only umutes with automation but not mute it.
so this narrows down the problem.
also when i stop the time ruler in the MUTED automation section envelop, than it mutes it and is does work !! .
so this means that it works on stop playing !! only not on automation.
when pressing space bar again to further playback than it umutes it normally according to the envelop until the next MUTE ENVELOP where it failed again on playback.
so if this is fixed i would be very happy.

hi thks for your reply.
 
that's is not an option, because when the instrument needs for sound to fade out, wile same tine i start playing an other instrument . than both instruments sound as long the fader of the just played instrument is not down yet.
plus that if i do this automated, than all instruments need to playing audio .
if i automate the midi fader than audio of the instrument also gets silenced to ??
whitish is strange ... why does a midi track fader influense the instr track sound and not the midi only ?
and can i change this .. that would be 1 option that could work !
 otherwise ... than i   really need midi mute !

it still means i need to press a key to use it and i want it automated in sonar, so i can play without to  press that key, and if i use this for instance 3 solo instruments, than i need to do this for all separately, so  no option here but thanks for coming up for a work around !
 
if one fader, knop, button can be automated than all fader knobs, buttons can be automated... they just forgot  to thinks about the midi track mute button, and i don't understand why they start with switch to automated mute. but did not finish it to work properly ??
and seems to be al owners of sonar have that problem so its not me.

I've been having the exact problem but with audio automation.  It works but if I start editing it, it doesn't automate in real time unless I click that section of the envelope.  Then the fader value changes.  But if I have the envelope as a fadeout, then it just gets stuck at whatever the last setting was.  Albeit inconvenient, I found a workaround by closing out the project and then opening it up again.  Then the automation works as long as I don't edit it.
 
This used to work without any issues.  I wonder if it's due to the most recent update (v24.09.0.29).  Prior to updating, I was experimenting with scenes and noticed that it wasn't recalling my settings when I switched from scene to scene.  The update fixed that issue, but then now I'm having this worse issue.
