We didn't make it to the Summer NAMM show but our friends at Synthtopia did, and they have posted this video of the forthcoming System 500 Eurorack modular synthesizer line, still in development by Roland.
We hear that the hardware has been finalized, what we saw at MESSE was not final builds. They tell us that the quiality of knobs/faders is greatly improved.
