Yes I'm experiencing the same thing here......
Works fine here using iPad and current O2 fw and app. Dunno about Mac.
Dave and Steve, what version of the iOS app are you using?
Could you try redownloading the Orba 2 app to see if the issue persists?
If it is, let me know
When I change Presets via the iOS app, the drum sounds don't change. There are effects and synthy strangeness on some presets, but the basic drums sound pretty much the same... nothing like an 808 or electronic kit like the Presets describe. All other instrument sounds load properly and are very different... but not the drums.
When connected to my Mac using the desktop app, everything loads just fine - very different drums with each preset.
Anybody else experiencing this?
