I started with littleFoot but its to basic to cover what I am looking for and to use the code editor is boring. On the other side the Blocks C++ SDK is so difficult to use with Swift that you need a bachelor degree. And yes I don't want to use JUCE because JUCE apps look and behave like alien on macOS. Coding is fun and should be fun with Roli Blocks as well. So why are you not providing a easy to use SDK or document how to use MIDI Sysex messages with Roli Blocks.
