Useful with Problems
I could use this to visualize many YouTube songs for free. However, the app doesn’t provide a very clear visualization for audios without high definition sound. I do like the free 30 songs I get monthly to polynize, and the crazy cheap subscription at only a couple dollars, but overall I would recommend this.

Oops
Error in processing YouTube says ... "Oops, new song ... " Having played with this app for 5 mins ... it seems like all the features are paywalled (no free trial) or simply broken.
Has potential
I can see this being useful, but it needs some work. I loaded an mp3 file of an organ part I am trying to learn. It is just the organ, no other instruments to filter. I’m on an iPad Air 4. The piano roll is so light and small I can hardly see it. That needs to be brightened up a good bit to make it visible. I like that you can slow it down, but it is just too hard to see. Hopefully the developer can fix this or offer a way to adjust the view. It would change my rating considerably. It is also possible that the app is confused by the Wurlitzer effect on organ parts.
