Now that the Jupiter-80 has been released into the wild, there are more demos being posted to show off what its capable of. Most of these demos seem to focus on the emulations of real instruments and effects, with less focus on the actual analog style synthesis capabilities. Roland have copped a lot of flack for using the Jupiter name on this one, so I'm guessing they are trying to demonstrate areas less likely to draw comparissons with their 80s flagship monster JP-8.
If you want a closer look at the synthesis, check out our interview with Howard Jones and the JP-80 from earlier this year.
