Hey,
I mentioned an editor for Max/Max for Live back in the winter. I didn't really get through to testers for some reason after some initial interest. This is a massive editor and already has been through a few iterations on my own. I decided to post it up publicly to try to get the final bugs sorted out.
Presently only the Max for Live version is posted. I need to re-arrange some objects and fix a UI glitch for the standalone. It may be a few weeks before I get around to that. In the mean time, Max 7 allows embedding a Max for Live patch inside a native patch and you just wire up the MIDI In/Outs and voila, you have a standalone editor.
