Description
The Sample Track sounds glitchy when automating the mute button on the track with an LFO Controller. You can mute/unmute manually and with the Automation Track and it's fine. You can also use the mute on the mixer and that will work even with the LFO Controller.
By judging from this part of a render of two sine waves, panned left/right, and one track muted via an LFO Controller.
The section is from when the right track is unmuted and you can clearly see that the signal is going on/off all the time when it should be just on.
#### Steps to reproduce
* Add a sample track and connect the mute button to an LFO Controller set to square wave.
* Play
Or just load this project. [sampletrackmute.mmp.txt](https://github.com/LMMS/lmms/files/12886091/sampletrackmute.mmp.txt) (Remove '.txt')
#### Affected LMMS versions
On master and 1.2.2

Research direction
Load sampletrackmute.mmp.txt in LMMS and reproduce the glitch by connecting the Sample Track mute button to a square-wave LFO Controller. Start by tracing the Sample Track mute handling and compare it with manual, Automation Track, and mixer mute behavior. Done means LFO-driven muting produces a stable signal without unintended on/off transitions.
