ALM Busy Circuits just released their Stem Ripper module - looks fantastic.. I'm not a builder but sometimes use Reaktor with my modular and hardware synths in standalone mode, just to experiment combining my little bit of modular kit and external synths with Blocks. Toy Box has an audio recorder which is nice but pretty rudimentary. I wonder if it would be possible to build an 8 input stem recorder like Stem Ripper and be able to drag those files into a DAW for editing/mixing.
