New to the iPad app, Patch Base, are editors for 4 vintage Roland synths: JV-2080, JV-1080, XP-80 and XP-60. Here's the story from a Patch Base spokesperson...
Patch Base 2.6 is available today, bringing editors for 4 Roland synths: JV-2080, JV-1080, XP-80, and XP-60. These synths were incredibly popular in the 90's, and have a lot of sounds that you'll recognize, just scrolling through the presets. According to Wikipedia, "The JV-1080 has been used on more recordings than any other module in history." And according to Legowelt, "If you program [the JV-2080], you can get some really freaky sounds out of it." Now with Patch Base, you can take these old machines to new (freaky) places.
Support for each synth is divided into two editors. The "Patch" editor is the standard synth voice editor, giving access to all voice parameters as well as copy/paste for envelopes and "Tones" (more on this below). The "Rhythm" editor is the drum kit editor, where you can create a kit with 64 different sounds in it, and shape each sound with pitch, filter, and amp envelopes. Check here for more details of the two editors.
Full support for each synth is available as an In-App Purchase, and the purchase of support for a synth unlocks both the Patch and Rhythm editors. For the next few days, these new editors are all 50% off.
