Advances in Bluetooth and personal Wi-Fi have benefitted the musician, but rarely their team of supporters. Producers or live sound engineers alike now have a new tool to work with in the UMMU Box v2. Like its predecessor, the UMMU Box v2 controls an audio console through a proprietary app, moving faders and changing the sound using a smartphone, as well as converting MIDI signals to UDP and vice versa. What the v2 adds is OSC compatibility and the ability to operate over a wi-fi network and without the assistance of an external wired router. Combined with products like the PUC, this can allow for a fully wireless MIDI studio. The UMMU Box v2 will be ready by the end of the year for those who pledge £130.
