After the release of Patch Base 2.6, I received many emails asking if any of those new editors would support some of the other Roland JV/XP synthesizers. Some of them should work interchangeably, but I told everyone that they should wait for editors for their specific synths before making a purchase.
Today Patch Base 2.6.1 is out, adding a few more editors to round out that family of synths. Today you can get editors for the Roland JV-1010, XP-50, and XP-30. And those 3 editors are each 50% off for the next few days, as well.
Also, the previous release was buggy in its support for the Roland SR-JV80 Expansion Boards, as many people discovered. This update fixes that support, and adds names for all of the waveforms on every expansion board, so you can browse sounds on all of your cards very easily. Enjoy!
