Its working fine in in normal folders, just not the new folder bus.
I honestly don’t remember if it was working in 15.0.20 and it stopped in 15.0.21
Thanks!
CORRECTION: The issue is sidechain inputs only. It also happens if nothing is connected, which might be expected since it not connected to anything routed to that group.
I am wondering if this is maybe the correct way. If the Midi track is routed to e.g. an Instrument track that is within the folder group, solo works as expected. If it is routed to something outside the folder group it gets muted.
The same principle applies to audio, group, and effect tracks. If they are routed to the folder group they get soloed, otherwise they get muted.
From my point of view it is not a bug but a desireable feature.
Even if I have the midi routed to a plugin or instrument inside the folder group, its the same behaviour. I tried different midi track routings and it does not matter. Regular folders work fine with midi, so I am just going to stick with that and route the old way.
Sorry, I just noticed that it DOES work if you route it to in instrument in that group, but it does not work if its only routed to a sidechain input. I am trying to route it to either vocalsynth or evoke, and it will not work on that type of bus.
For some reason, it will solo properly if its only routed to a sidechain in a normal folder.
I did find a workaround though…just use solo defeat.
