These were limited to just 90 units worldwide. Grab one before it's gone!Future Retro is no longer manufacturing equipment but they are still offering warranty on the Vectras.
The Vectra is a unique digital-analog hybrid synthesizer providing four oscillators, white and pink noise sources, four ring modulators, a four-channel mixer, five LFO’s, six morphing envelopes, six primary multimode analog filter types, a main analog VCA, and numerous internal modulation routings and VCA’s controlling modulation amounts.
It really is like having a powerful self-contained semi-modular synthesizer with approximately 500 internal signal routings, and around 256 storable sound parameters.
