It has polyphonic Violin and Viola waveforms as well as monophonic Bass and Cello waveforms. It is split into 3 sections: Strings, Synthesizer, and Bass synth - all simultaneously available. It has traditional and simple VCA, VCF, and LFO controls for contouring the sounds as well as a chorus that thickened the string sounds. The Omni had two oscillators per voice as well, but there is no program memory."
