Asked about MuseSounds Drumline on Linux a while back, looking for an update

The title says it all! I asked a few months ago why there was no MuseSounds Drumline in the MuseSounds Manager app for Linux, and was pointed to the 4.4 announcement which said it's not available yet, but it is being worked on. I do understand that there are almost certainly more important things being done, and that as a small platform, Linux probably isn't worth the resources, but the wait is killing me, I really want to try out these Drumline sounds without needing a virtual machine!
