For all its polyphonic goodness, the Roland Alpha Juno 2 might be starting to show its age in terms of its LCD character display. Thanks to this display being compatible with the Hitachi HD44780 protocol it can be swapped out with an OLED display for crisper, clearer reading.
Sure, this could be a hack for all us synth-heads who want a better display, or more practically for those whose LED displays are starting to fail. And Jeroen Oldenhof figured out a way to upgrade his Juno 2’s display which he kindly details in this article on his site here.
Warning: there is minimal code to replace.
The Roland Juno series of analog synths played a large influence on European hardcore techno from the 90s and has been used by artists such as Vince Clarke, Pet Shop Boys, The Prodigy, Massive Attack, and Paul Hardcastle to name but a few.
