@hearsepileup - While not subscription based, I have found that the Linux version of #Reaper is the best DAW to use (as a bonus, it handles Windows plugins run via yawbridge really wonderfully). Another option that works very well in Linux is #Ardour, but it is not nearly as intuitive. Finally, there is #QTractor, which I like quite a bit, but it is not as robust as Reaper and Ardour.
