I remember that Moog did not even allow to use its name and the name of the synth. Atom then called his panel for the Moog Voyager “Mougue Voyeur”. It really depends on the company. I have never heard that any other firm had such a problem with that. Well, Steinberg would probably take you to court but in the case of Roland I think they don’t care too much. Maybe they are even pleased that someone is working for free to improve one of their devices. If you want to be sure you can ask Roland for permission.
