No Roland logo and calling it JE-8086 when they're involved? Still possible, but rather unlikely. Who knows.

Any patents that were tied to JP8k have long since expired. Emulation is fair game. Decapping CPUs is not illegal and since it's an electronic circuit, it cannot be covered by patents, so Roland cannot sue for someone reverse engineering how the chips themselves work.

It's completely legally in the clear.

Great work once again.

Any info yet on the CPU hit compared to their other emulations? Most of them are pretty good on my machine, the Nord one I can only run four instances of.

No details yet. The demo they posted has 32 instances going, so it stands to reason it's less CPU intensive than current DSP563 emulators.

32 instances, or 32 audio tracks?

Instances.

Is that running on the connected network thing? 32 instances. I realize these guys are devs with high power computers but I can barely run 3 emus on my i5 before it starts smoking.

Fact is: Back in the year 2004 JunoX was removed from the market.
Roland's lawyers had taken action against reFX. Reason: The 'look and feel' of the product and the 'name' would be too similar. JunoX was replaced with Vanguard.

Because of this ugly GUI? Hard to believe.

It is what Roland's lawyers essentially had written back in the year 2004. Mike (the owner of reFX) removed the product from the market quickly as things can get very very expensive if you get sued.

It was purely the name. It def didn't look or sound like a juno.

I remember that. But it wasn't designed by Michael. Some upstart hotshot kid was behind it. Wonder whatever happened to him.

Regarding the firmware, surprisingly, the JP 8080 firmware is nowhere to be found on the Roland website.

However, the JP 8000 firmware is still available.

It's hard to understand why it's still the JP 8000 firmware and not the 8080 firmware.

There were far more patches and performance improvements on the JP 8080.

but how do you get a firmware to the pc when you got a JP8080 still?
