Instrument patch unmuting other tracks in Logic Pro

Thanks, John.

Yes. In this case, I'm experimenting with an track called "80s Bitrate Synth". I have that track with the Solo button on (a white "S" on a gold rectangular background).

Whenever I load one of my user patches onto that 80s Bitrate Synth track, and then press one of the keys on my controller keyboard to test how the instrument sounds, nine of my other tracks which I had previously muted become unmuted, while four other tracks which I had muted remain unmuted.

I wonder if I had unknowingly created a stack of those ten tracks that are (via the Mute button) connected.

I'm new to stacking of tracks, so I haven't yet purposely tried to stack any tracks. and I'm unfamiliar with how track stacking works.

Yes, my selected track and several other tracks are set to Solo.

But whenever I switch to a different patch on a selected track, four other tracks which were muted (always those same four tracks in this particular song) become unmuted automatically. It’s frustrating.

It happens when I switch a patch on a particular track and press a key on my controller keyboard. Suddenly all the Solo tracks plus the four previously muted tracks (which are also Soloed) begin playing.

I tried Mix > Automation > Delete Automation with each of the five tracks involved selected (one track at a time) but the problem persists.
