"Tweleve Gates to the City" performed by Don Lewis featuring Roland's amazing Vocal & Ensemble Keyboard VP-550.
Much more than a traditional vocoder or harmonizer, the VP-550 uses Rolands breakthrough vocal-modeling technology to bring the highest-quality, interactive vocal sounds to a dedicated instrument. Connect a mic, select a sound, and play. You wont believe what can come out of this instrument: spectacular classical choirs, soulful gospel choirs, pop and jazz voices, male & female ensembles, vintage vocoder, and lush string/vocal hybrids.
