Some people have heard of Sonobus, but have you heard of Satellite plugins from Mixed in Key? It's supposed to give collaborations from within your DAW, but, it's not working for Cakewalk DAW, it seems only for Ableton Live, Logic, Pro Tools, and FL Studio, but trying it in Cakewalk, there is no BPM syncing between plugin and host, and will keep telling you to change host BPM, and won't let you go any further.
