Hi there,
I'm not using them professionally or as a hobby or anything, but I think they look really cool and I have come across a few but they look more like they are meant for professionals to analyse the music rather than looking cool (which I know that's probably not what they were originally intended for, but I think they look cool so I would like to have some software for it)
Thanks
I did not find the right solution from the internet
