The idea behind the GO:MIXER from Roland is for mobile music makers and video takers to be able to capture better quality sound. In short, bands will be able to perform and have their audio mixed while being recorded on video on a smartphone. Interesting.
Here's the official press release from Roland at CES 2017.
CES, Las Vegas, NV, January 4, 2017 — Roland (booth #18138, LVCC Central Hall) has introduced GO:MIXER, a compact audio mixer for smartphone video production. Compatible with iOS and Android smartphones, GO:MIXER connects digitally via an included cable, providing clear stereo sound that’s a marked upgrade over using the phone’s built-in mono mic or analog line input. With multiple inputs available, users can connect a mic, musical instruments, and media players, and mix them all together live while they shoot. Ultra-portable and simple to use, GO:MIXER is the ideal solution for adding a pro sound touch to social media videos.
With the great video quality of today’s smartphones, capturing music performances and other types of content has never been easier. However, recording a high-quality audio soundtrack along with a video has typically required complicated external gear and time-consuming editing in post-production. GO:MIXER greatly simplifies the production process, enabling users to capture audio directly to a smartphone video in real time.
Offering plug-and-play convenience, GO:MIXER is ready to use out of the box. It’s powered by the smartphone connection, so no batteries are required. And with a compact size that measures just 3.75 inches (95 mm) square and 1.1 inches (28 mm) tall, GO:MIXER is perfect for desktop and mobile use.
GO:MIXER supports connecting up to five sources at once via inputs for a vocal mic, guitar/bass, stereo keyboard, and two stereo line-level devices (such as music players, drum machines, etc.). Front-panel knobs provide hands-on mixing for the mic and instruments. There’s also a stereo output jack for monitoring the sound via headphones or an external amplification system, plus a dedicated panel knob for adjusting the monitor level.
One of GO:MIXER’s line-level inputs offers a selectable Center Cancel function, which reduces the volume of the main vocal in a music track that’s playing through the input. This is a great feature for singers, allowing them to create karaoke-style tracks on the fly.
