Project overview
The Orbital Device sounds are definitively from outer space and will take your brain out of this world. The EQD Grand Orbiter Phase Machine inspires this all-analog, true bypass, 4 stages OTA-based phaser.
Introduction
3, 2, 1, Liftoff! The main engines ignite the entire orbiter clatter and shudder like a skyscraper in an earthquake. A deep rumble jolts the cabin as the main engines come up to full thrust. You and your crew are ready; you are going up in search of the ultimate cosmic sound. Lucky for you, the Orbital Device has a resourceful panel control that gives you the ability to craft and fine-tune the exact effect you’re after:
This 4 stage OTA-based phaser has a diverse feature set that can go from motionless and resonant to slow and smooth and on through fast and elliptical.
With the Three-way toggle switch, you can select between different ranges of modulation. Try a slow, clean sound with the Rate 1 mode. Kill the LFO and use the Orbital Device as a fixed resonant filter with the Rate 2 mode. Finally, change to a fast sweep mode with Rate 3. Altogether, control the fine-tune speed of the LFO in each of these modes with the master Rate control. The flashing LED acts as a visual indicator, even when the effect is in bypass mode.
Use the “Phase/Vibrato” switch to make a true pitch vibrato; when in “Vibrato” mode, the dry signal is removed, and the Depth controls act as a volume control.
The Depth control blends the shifted signal in with the dry signal and controls the effect’s intensity. The Rate control fine-tunes the speed of LFO. With Sweep, you will able to control the frequency range. And the Resonance controls the effect regeneration.
This phaser will sound interestingly different when placed either before or after distortion, with spectacular extragalactic results either way!
