The day I see it, and see it working well, I guarantee I will be getting it, I will even have to buy a Windows laptop to run it, and won't feel bad doing that!

I still think that a simpler product, that merely took the NTA output MIDI channel, and looped it back into your arranger after Chord Sequencing it would be the simpler product, with a wider user base, but if I have to get the full vArranger, so be it...
