Well, every manufacturer of digital boxes could do that. So we might think about why it doesn’t happen regularly…
It might be because the hardware design, the buttons, display, and all, in such a box is made to fit exactly the designed purpose.
I dont know much about a digital synth’s internals - it might be that everything really just works in software, so these things are just computers with a firmware and some controller knobs. But digital doesnt necessarily mean “all software” - it might also be that there are some functionality-specific digital chips inside. Special kind of digital Signal processors, where one is needed for a sampler, but a completely different one for a digital drum synth. At least a sampler needs more memory chips, whereas a drum synth probably needs more processing power. Take a screwdriver and get a digitakt and digitone and see what’s inside
These are already nearly the same cases. But are they the same inside, too?
If it’s feasible, elektron would have done that with these devices - developing hardware is expensive and brings a lot of risk for failure, and if they could sell the same hardware twice with just different software, they would likely do it. And than they could also offer this “firmware crossgrade” especially for these two.
Maybe a bunch of people willing to just spend 200€ to sometimes be able to convert their digitakt to a digitone or vice versa.
Then I wonder, how far this idea is from “some kind of small computer plus a good multi-purpose controller or two”.
Wouldn’t this be nearly the same as having a iPad or Mod Duo X or an organelle plus a controller with some knobs and faders - eg AKA MPD232 or something similar?
I’d actually prefer one of the latter then - Open Source, so I can change whatever I want to my needs, while I pay for the polished package that works well immediately without setup and configuration fiddling.
But I also like to have specific-ability hardware boxes for immediate access to the sounds and workflow i like most, without any firmware exchange process, or touching a computer. I think that’s what I have hardware synths/samplers for. (not a purist, for other purposes/moods/parts of the process I have and love Bitwig)
