The Roland SVC-350 is a classic 11-band analog vocoder produced between 1979 and 1986. It is celebrated for its ability to merge a human voice (the modulator) with an instrument (the carrier) to create robotic voices, lush vowel-inflected pads, and classic 80s synth textures. 

• 11-Band Filter System: Provides highly precise and clear reproduction of consonants and vocal articulations, avoiding the "muffled" quality of some digital emulations. 
• Integrated Ensemble Effect: Features a built-in Bucket Brigade Device (BBD) stereo chorus circuit that adds incredible width, thickness, and spatial movement to the synthesized sound. 
• Dedicated Instrument Inputs: Includes specialized inputs for microphones as well as electronic instruments (like synthesizers or guitars). The guitar channel features built-in compression and harmonic generation. 
• Footswitch Controls: Supports remote switching for Vocoder/Direct signal routing and the "Hold" function, which freezes a specific vocal tone or vowel to allow the singer to breathe without the effect dropping. 
• Graphic EQ/Voice Character Controls: Allows you to shape the overall tonal flavor using sliders on the front panel. 

Famous for its use by legendary artists ranging from Kraftwerk and Vangelis to Daft Punk, the SVC-350 remains a highly sought-after piece of vintage studio equipment.
