So plenty of tasty looking stuff coming out of NAMM...this one caught my eye (via Bleepology):
MOTU have announced a piece of software that allows you to send CV out via a compatible audio interface with DC coupled outputs (e.g. MOTU Traveller 3, RME) for control of analogue synthesisers and modular systems. There's been a bit of info online as to how to hack something like this together yourself but they seemed to have a high attrition rate on the audio interface (shorting capacitors etc.) so it's nice to see official support.
