Looks like Roland are expanding the sound set for the flagship Jupiter-80 synthesizer - with this teaser video for the Jupiter Legacy Collection they appear to have been working on a new sound library to bring in a load of their classic synth sounds including the original Jupiter 8, JP-6, Juno 60, Juno 106, D-50, SH-101 and TB-303.
The teaser is very specific about the Jupiter-80 Host Mechanism, so it doesn't look like this will be available on the more keenly priced Jupiter 50, but time will tell.
Pricing and availability is TBA
Developments for Korg's instrument have been slow but promising.
