I always post here with trepidation because all of you are probably more advanced than I am, and I don't like asking silly questions, but here goes

I would like greater control of the drum mix than a single fader offers. BIAB 2022 has the ability to have stems. I read the notes and viewed the tutorial and opened real drums picker and chose a style with stems. I chose first to include the mix and then tried it without. In both cases, individual drum tracks appeared in the mixer window. However, The only one that could be heard was the mix channel. If I tried adjusting any of the others, nothing would happen.

When I brought the stems in without the mix, nothing played at all, no sounds were even being registered by the meters
I think I followed everything from the BIAB tutorial and also a youtube video by journeyman. Is there something I am missing?

I am using BIAB 2022 64-bit/ If it helps (though I have not used it for this) I am also using Reaper as my daw
Thanks for any assistance you can offer
