Released in 1989, the ensoniq vfx synthesizer was ensoniq's early take on wavetables, called transwaves in ensoniqs' perlance. The machine was a digital six oscillator hybrid rompler and additive with several of the waveforms being wavetables. Modulation settings allowed you to scan thru the waveforms for evolving sounds such as this pad. The vfx-sd was much the same synthesizer, but added a sequencer.
