AUX Channel MUTE button behaviour during playback

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

1. open the mixer in MS
2. activate (unmute) the AUX Channel of the internal Muse Reverb
3. start play of a mscz file and you should listen reverb sound as expected
4. press MUTE button of the reverb AUX Channel but unexpected, you will continue listen reverb sound
5. it seems as if the MUTE button was not activated, but it is activated, because the button color changed over
6. there are two alternative methods to activate the MUTE button function to stop the reverb: either a)when you stop playing and start play again, then there is no reverb sound, or b) during playback put the mixer fader of this reverb AUX channel to ZERO, when you then return it to any level there is no reverb sound
7. if you unlock the reverb MUTE button, you will listen reverb sound as expected
