The company #Pioneer DJ made
- a freely downloadable magazine ('deckades') to chronicle the evolution of DJing over the last 30 years, which is noteworthy because Pioneer used to dominate clubs and festivals because it used to be THE professional DJ standard https://blog.pioneerdj.com/pioneer-dj-history/30-years-of-the-cdj-get-your-digital-copy/
- and, separately, a blog about the 15-year history of their software Rekordbox, which is currently, after all these years, rather hated because of 1) the subscription model which was newly introduced in 6.0 and forced onto users without an acceptable way to downgrade, 2) its unnecessarily dropped features for older #PioneerDJ hardware models, and 3) its main new feature 'stems' in 7.0 which is a great novel idea, and hyped endlessly, but implemented so poorly that I know nobody who actually uses it as designed https://blog.pioneerdj.com/pioneer-dj-history/we-look-back-on-15-years-of-rekordbox/
Personal note: I should really do some research to find out how much emulation exists in free software for Rekordbox features (like export to USB of a mp3 library with presets)
