I have recently discovered this little FREE gem. It's a 100% clone of the original hardware (reverse engineering of the original chips) and load all sound cards from the JV-era, so you can gets tons of sounds.
I have tested it on my Mac and it works perfectly. Pity it doesn't have any control on the sounds/presets, so at the moment it's just a preset "player", hopefully the hardware part (controls, menu) will be implemented in the future...
It's freely downloadable from https://github.com/giulioz/jv880_juce but you'll need to find the firmware(s) on archive.org

That's awseome , the jv880 together with the jd990 are the best sounding romplers Roland ever made , to this date
Hopefully he tackles the jd 990 next
Up-and Running ..comparing it to my Integra ...the sound is there

This guy's emulation stuff is super cool, you should check out the RD Piano (MKS20 emulation) and his Boss Microrack series projects too...

Very cool! I have a JV-880 myself, so I’m really interested in this and how it develops.

It would be great if this editor for the hardware could somehow tie into the plugin, but it's probably not possible:

Apparently, that is a CTRLR panel, but who knows. Techically it could be done using MIDI maybe?Examigan wrote: Sun May 04, 2025 10:04 pm It would be great if this editor for the hardware could somehow tie into the plugin, but it's probably not possible:

You de-quarantined and code signed it? Rebooted?
It (the AU version) works here everywhere other than Logic, where it just crashes hard in the process block every time…
