Last year I stumbled across a video of a patch (I think) was made with Max4Live. If not, it was Max/Msp. I've been hunting for this video for yonks and cannot find it. From memory, the software allowed you to input a melody and then it was able to harmonise other lines and then modify them and change it's voicing to create counter melodies and other instrument parts etc. Handy for quick orchestral composition.
Anyone know what this was called or any info where the video is? That would be awesome!
