The latest project is to remove my reliance on Traktor for DJing. I think it's possible to make something which automatically keeps 2 or 4 tracks in time, without having to constantly adjust them. All it takes is a little preparation beforehand - such as inserting a few simple tags into the soundfile. The DJ would then be free to tweak various crazy effects - another thing missing from Traktor (the version I use, at least.)
I hope to have it on the go by the time I get to Switzerland! Maybe not with all the effects but a basic working version at least. I need a name for it though. So far I'm torn between "Kombine Harvezter" and "Trowel."
