Jeff Rebrovich (aka GHOST SYNTHESIS)
Artist, Composer, Sound Designer


After years of playing in various bands and other various musical incarnations, as well as being fortunate enough to share the stage and studio with some of the finest musicians the world has to offer, Metro Detroit native Jeff Rebrovich (Ghost Synthesis) made the decision to put those endeavors on hold in hopes of trying something different. “To be quite honest, I didn’t have the money to properly pay anyone else to help me bring these ideas to life, so I took some time to try and teach myself as much as I could and learn as much as I could from anyone willing to show me anything at all about music production, programming, etc”. “I think I called in every possible favor I could in order to get those first projects done.” With new music being recorded, traveling the world, new collaborations and opportunities in the works it’s certain that Ghost Synthesis will be a little bit of everywhere in the coming months and years.

“iKeyboard 5X is indispensable when using it with MIDI capable analog gear.”

“My first impression right out of the box was the build quality. For a slim bodied controller I was pleasantly surprised and pleased that it had some weight to it. I needed something to hold up well on stage as well as in the studio, that left a small footprint, yet versatile enough to encompass multiple applications, whatever hardware I may be using and whatever DAW I was working in. The keys feel great, and having both five pin and USB midi always a plus, and the fact that all of the controls are in one spot makes it easy to almost memorize what your hand needs to press. Just the transposing function alone makes it possible to do things that either took menu diving or saving presets or inventing creative solutions with tuning oscillators on the fly.

“The two things that I’ve found most useful is how easy it was to change the midi channels, which makes using gear with fixed channels or using and switching between multiple channels much easier. And the transpose function when using any midi compliant analog gear is just brilliant. No menu/sub menu setups, no saving, no finagling with fussy oscillators. It just does what it’s supposed to do. Interesting how one piece of gear has single handedly helped get this new project up and running faster just by being efficient and as I stated already, by doing what it’s supposed to do. Fantastic unit.”
