This vintage VFX is fully functional and in good condition. The keys are a bit yellowish in color.
Following up on the heels of the ESQ-1 and SQ-80 synths from Ensoniq comes the VFX with more polyphony and waveforms. The VFX allows for PPG-like synthesis using a sort of wavetable synthesis. This puts it into a unique class of digital synthesizers along with the PPG Wave series, Waldorf Microwave series, and Ensoniq SD-1, SQ-80, ESQ-1, and Fizmo.
The VFX has 21 voices of polyphony. A single patch can contain up to 6 of 109 waves in its ROM memory that can be combined and layered. Advanced and analog-like synth parameters including its dual multi-mode digital filters, three 11-stage envelopes, LFO, and 15 modulation sources allow you to further shape and morph your sounds. There's even a built-in 24-bit VLSI dual effects processor with reverb, chorus, flanging, and delay.
The VFX has a standard 61-note keyboard with velocity and polyphonic aftertouch. The synth also has full MIDI implementation with 12 channels for multitimbral functions. The VFX has a cartridge port as well, for storing sounds onto Ensoniq's proprietary media.
