I think you’re referring to Yuri’s videos, OP? I guess you’re posting this because Yuri is using a similar video style as RMR but is getting a lot more views? I don’t think you need to be upset about this… I find both RMR and Yuri make great videos and enjoy both; you don’t need to try to make this a fight between creators.
In terms of the information density and musicality, RMR is (in my opinion) putting out higher-quality, more entertaining content. And he did popularize the recent style of showing the music-making process in its entirety on the OP-1.
But for the average viewer, they’re going to find Yuri’s videos more entertaining because they’ll recognize the samples used and are interested in seeing how those are manipulated. Most people are less interested in the actual music-making process, and will watch the videos for the novelty factor.
I don’t think it’s fair to say he’s “copying” RMR in the video style; using a top-down view for synths has been around forever and even the original use of the OP-1 in the One music video was in the same view. There’s definitely no legal issue here, since it’s not a style that either creator can claim they started.
I think it’s just great that we’re getting to see some solid musicians making music on an instrument we all enjoy using!
