Ean Golden

In this video tutorial on packing a DJ gig bag, approximately 4:50 in, Ean says, "the next thing I wanna show you goes out to those of you who are using external sound cards, like this one." An annotation then pops up that states that Ean's sound card is the Fireface UCX specifically.

Additionally, the telltale side-handles of the Fireface can be spotted a few times earlier in the video; however, it's most clearly identified at the 4:50 mark. Ean Golden owns and runs the company who runs this YouTube channel, so the annotation can be considered authoritative.

Ean Golden is the designer of the MIDI Fighter line, including the MIDI Fighter 3D. Throughout this video he uses the MIDI Fighter 3D to trigger drum samples alongside the MIDI Fighter Twister.

In this video, Ean demonstrates how the Maschine can be synchronized with Traktor to perform various tasks in live performance. The left side of the unit has one large knob instead of three smaller knobs, so it is distinctly the MkII model.

Ean Golden is the designer of the MIDI Fighter line of products, including the MIDI Fighter Pro. In this video, he demonstrates a controllerism routine on two of the early models of MIDI Fighter Pro.

"Making new music in the studio and the sound is really, really, BIG! The tracks are all built around the same drum patterns I play live in this set" - Ean Golden.
