Would be nice. The point was that the stem separation models certainly are open. It could be integrated in Mixxx (if it isn’t already, it should).

Compared to the prices and licensing hell of NI and other dj brands, just paying 35 euro for a perpetual license to solve a problem and always have the best models delivered to you is actually nice. The price is fine for what it does and the consistency, support and positive energy that comes with it.
