Now here's something just for the fun of it! Since this is quite popular right now (and hotly debated and quoted on reddit for example) I decided to try my own glorious MIDI art. Since my Logic Pro 9 has this neat function "View>Show Region Colors" I decided I'll try a multi-layer, multi-colored version of this. And that's what I came up with …
… using the simple app Overlay 2 I carefully traced back every color separation of Leonardo Da Vinci's Mona Lisa and assigned to each region the corresponding color.
Since the multiple colors needed to be on separate tracks I decided to use an actual beta version of AutoTonic which will allow of multi-channel processing (still not official, it is in the making!). After creating my needed 18 virtual MIDI ports (8 in/8 out) I sent each regions signal to separate instances of AutoTonic having all the same template loaded so I can switch Headers from one global MIDI input port.
Since the Mona Lisa just looked better on the piano roll's black and white key rows I decided to leave them the way they were but instead to fix the signals on-the-fly, right before they enter AutoTonic, using a simple utility transformation in Logic Pro, so no black key signals - and therefore any Headers - will be toggled.
This allowed me to change Headers afterwards, at the moment where I already was listening myself/recording the whole transposing result. Here's the video link of that nightly session:
Besides 'how useful all of this really is', it is at least possible to do … and even though not being always so much fun to set up and still the sound result itself didn't always sounded pleasing to me, I was quite happy to accomplish in the end what I had in mind.
