Following on from the above - I struggled to find a working sketch that shows how to accurately isolate specific frequencies within a spectrum when using MINIM to analyse audio for responsive visuals. 

I've uploaded a sketch template  here that I'm using as a base at the moment, it's not much to look at but because a lot of examples I found were overly complex for my noob self, I stripped this down to the bare essentials using simple blocks, lines & points.

It's quite heavily commented and I hope it can be helpful to some. I'm sure it can be refined and optimised a lot more.  

It seems as though the audio isn't working in the browser so best to download, I've included the audio track in the source.

I did actually use the sample code from your workshop, it's just not that clear in this latest video as I played more with the bend / twist functions for these (which are awesome btw). The workshop is linked in the Vimeo description, but quite far down, so I hope people don't miss it :/.

If you have a peek at this video you will see I used Modelbuilder too (this was my first stab at using the library) - in the beginning from 00:10 & interspersed from 01:16 onwards (the video is a mixture of visuals made with 3DS, Cinema 4D & Element 3D by Eaton Crous and Processing by myself). This Vine shows it slightly better.

I found your workshop extremely useful, and a lot more elegant than the method I was using before. Will be using this as a base moving forward. Not saying I fully understand how everything works yet but your explanation above further clarifies a few things for me.

Thanks again, I may bother you with a question or two in future if that's ok!
