Gemini GMX DJ Media Controller System

The GMX is more than a DJ MIDI controller and interface -- it's a standalone player, too. Spin tracks from your laptop's DJ software or plug in a USB stick.

The Gemini GMX is a versatile multi-format media controller for the DJ who desires portability and multi-functionality. DJs can playback tracks from a single USB drive or from a laptop as a versatile software controller for Virtual DJ or another host application. The eight large performance pads on each deck and the touch-sensitive mechanical jog wheels ensure inspired and intuitive control over every aspect of playback.

Touch + Data = Precision Control

The high-resolution USB/MIDI data-stream contains 14-bits of continual control information. That means every turn of a knob or jog wheel can have the precision of 16,384 possible level settings. With that much precision the GMX is the ideal choice for precise pitch and tempo control or any other function you desire to mangle within your software.

Spin Files from USB Memory Devices -- Laptop Optional!

Direct playback from a USB memory device of MP3, WAV, AAC, and AIFF files allows the GMX to be unchained from the laptop. Its portability will inspire spontaneous sessions and make for fast and simple setup at smaller venues.

Balanced XLR and RCA Outputs

As an independent media player or as a 24-bit PC/MAC audio interface over USB 2.0 the GMX is professional from the inside out. With multiple high quality output options: monitoring, recording, and playback through a sound system are simultaneously available via balanced XLR or RCA outputs.

Scratch and Cue Precisely on Jog Wheels and Pads

The GMX's read more mechanical and touch-sensitive jog wheels allow you to reach higher levels when it comes to scratching, beat juggling, or finding track points with precision. With advanced tools including: Hot Cues, a Loop section with Auto and Manual Loop, Reverse, and dedicated Filters on each deck, the mix decisions you make are instantly realized at the push of a button.

The Big Picture: See Your Mix on Waveform Displays

The high-contrast screens with adjustable waveform displays allow easy visualization of the changes you are making to each of your tracks.

I was super excited about this purchase, did a lot of research before ordering. The versatility of this controller is what sold me. I liked the idea of being able run a flash drive instead of having to be tied to the computer. This thing has two pretty major issues. When using the stand alone mode with a flash drive, there is a very noticeable pop and skip in the track when loading a cue track. sometimes the track will even skip to a different position in the song. Ive tried changing flash drives, different folder arrangements, number of tracks on the drive, file types, etc. Nothing has worked so far. This bug renders the stand alone mode annoying at best, and unusable in any type of live setting. The second issue is in regards to VDJ. Using the factory mapping, and gemini drivers, the playback channels (headphone, master, etc) get switched around by the software. Sometimes it works as it should, sometimes it doesn't. Sometimes the headphones work, sometimes they do not. Sometimes, the channels are backwards. I have tried reinstalling VDJ, Updated the drivers, updated the unit with the gemini updater, tried many different asio audio settings. Ive gotten it to work correctly, saved the audio profile, and when I re open VDJ the settings while the same as before, do not function correctly. I have emailed Gemini several times, but none of the advice they provided was any different than the user manual. They did not address the popping or skipping, only addressed the VDJ issues. read more None of which helped me out. At this point, the GMX is sitting in its box, and I am out of ideas. I have two payments left to zZounds, and am past the return deadline. There is little to no info online, and no forum support either. I am super happy with zZounds, and will purchase more in the future, but am extremely dissatisfied with the quality and support I have received from gemini. As I am unable to use it, or return it, it will sit in its box in my studio indefinitely.
