@DjOsZ Thank you very much for the info.
I totally agree with your point of view regarding the features and functionality of Mixxx in relation to Engine OS. Denon has shown that software development, unlike hardware, is far from its strong point. The waveform analysis engine, bpms, etc. of the tracks, the interface, and library are tremendously basic, almost, I would say, like a kids app. Support and updates are very slow, do not meet user demands and with each supposed improvement or step forward, new bugs appear and two steps backwards.
Therefore, I also agree with your opinion (it is not a crazy idea) that if, tomorrow, I had the opportunity to install Mixxx on my Denon SC5000M unit, I would do it immediately with my eyes closed.
At this point, and with all due respect, the Denon developers having not shown that they are competent and up to the demands of software like Mixxx, VDJ, Traktor or Serato, I would also quickly suggest to Denon/inMusic alliance or acquire Mixxx, or else its units, at the software level, will never reach the desired sales and impulse, to compete with brands like Pioneer and their Rekordbox software.
If anyone else could share their experience exporting Mixxx on their Denon Prime series player or controller, or ideas or future projects, I would be greatly appreciative.
A greeting.
