My only caution about moving to the box is whether you want to be able to go back to old work, and indeed old workflows.
I’m in my 40s. It seems like ten seconds ago that I was in my 20s.
Things I did on hardware in my 20s are there as if they were made yesterday. An mc303 is unchanged, and the backups over sysex restore just fine. I’m confident that any backup of the CF card in an OT, or the SD card in an M8, will work fine on any working unit in 2043.
By contrast, things I sweated over lovingly in Cubase with VST instruments and effects in my 20s are now completely inaccessible. The MIDI patterns are there, and so are vocal takes as wavs. But almost everything else is gone: the perfect synth settings, sampler edits, sound design, effects and compressor settings, much of it lovingly automated… they are all effectively gone forever, because they’re all done in plugins that no longer exist to buy or download, and certainly don’t exist in forms that can run on a modern computer. I mean things like… Groove Agent 1, some Roland orchestra thing, an ancient weird organ thing, DiscoDSP ThrillMe, random built in plugins, niche things I found for free, and more. Maybe if I had only used Waves plugins that stuck around forever things would be different, but that’s no fun, and anyway I have no time machine to predict those things. Maybe if I’d been really discplined about printing stems to wav I’d be fine, but I wouldn’t be able to modify any single thing about any one of them. I have full rendered tunes, that’s all. That’s not all I made tho. Think of all your fun noodles that you want to return to.
In addition to this problem - losing my archive, really - I’m currently not updating MacOS because my Ableton 9 and NI instruments bought only a few yrs ago would need upgrading, at very huge cost. My Moog MG1, Jupiter 4, my old hardware compressor, my early 2000s eurorack, do not present this problem. I just switch them on and I can use them.
So, for me, hardware is forever, plugins - I am very aware now - are only for now.
