> And RekordBox does not run well on Linux RekordBox doesn't even run well on Windows, so hard to imagine what worse looks like. But yeah, if Mixxx (or other FOSS software) could offer writing playlists into USB sticks, I'd get rid of RekordBox yesterday because few software out there works as bad as RekordBox.
I considered renting out some Pioneer equipment to add RekordBox playlist writing support, mainly because I'm in a similar situation. Mixxx does have support for reading USBs & SD cards, but not writing ;_; Unfortunately it's far down my priority list given the cost, my unfamiliarity with Mixxx development and that I rarely do anything without Mixx. But this is absolutely what ecosystem grants/bounties should be for.
BTW, the DJ collective I'm with has Pioneer CDJ. If anyone need use the hardware let me know. I'm trying to get them to start using open FOSS software, but it is hard.
