The Minimoog Voyager XL was released to celebrate the 40th anniversary of the Minimoog Model D. The Voyager XL builds on the original Voyager models but expands the keyboards to 61 keys and adds a ribbon controller, an additional LFO modulation bus, and a modular patch bay. Each Minimoog Voyager is inspired by the original Minimoog Model D released in 1971 and features 3 wide range voltage controlled oscillators, one noise source, 2 resonant filters, an external audio input, 2 ADSR envelopes and an LFO among other classic traits.
