Digital Audio Workstation (DAW) for people who want to record, edit, mix and master audio and MIDI projects. When you need complete control over your tools, when the limitations of other designs get in the way, when you plan to spend hours or days working on a session, Ardour is there to make things work the way you want them to.
Fruity Loops doesn’t have any easy equivalent on Linux. I’d say try reaper and ardour as they provide windows binaries. Be careful LMMS isn’t a FL clone, it’s midi only.
For the Arturia plugins you can install them with wine and use yabridge to make them compatible if they are not in vst compatible format (ardour can take vst2 and vst3 but sometimes it will not work). You can also have a dedicated PC for instruments (it is what I do) on windows (using audio gridder). Gotta test the Linux server version of audio gridder to see if I can go back to linux on m’y second PC. Or you can just send the midi notes to pc2 then get the audio out to pc1.
It’s doable to make proprietary plugins run on Linux but the reliability is the nightmarish part, as an update can break the wine compatibility and it can take a few mins/hours to restore.
