I was contemplating starting work on a sequencer (owing to the lack of a good functional sequencer on Linux platform), but I was not sure how big of a copyright violation it might be if the interface looks very similar to tracktion and/or Live. Any ideas? I think the particular source and binaries that Mackie and Ableton makes are under copyright, but not the entire interface styling, workflow and the features?
To be more specific, I’m thinking a sequencer with the same basic screen layout (ie. a browser tab, a studio tab, a settings tab). The studio tab has the track view, bottom area has context-based controls, left part has common command buttons at the bottom and track names, inputs etc on top, right part has track outputs and insert effects (maybe in the same style as tracktion :D). There might also be a mixer screen and a DJ screen to play loops like Ableton. Most of the interface will probably end up looking similar to tracktion, with some of our own widgets and ideas as seen fit.
Is this possible, or am I walking into dangerous territory?
