The gMIX is a minimal four-channel stereo mixer, designed for mixing the output of anything with a headphone jack.
It uses a passive design, so it can run without power or batteries. Here’s the official intro video:
The gMIX features four 3.5mm stereo jacks, which you can use to plug in just about any modern electronics with a headphone output, including Korg Volcas, iPads, iPods, KAOSS pads and many other devices. Each channel gets a volume control and that’s it.
The gMIX is being developed as a Kickstarter project and is available to backers, starting at US $35.
