This is Strobe's "Utopian Mystery II" (Winter Chip IV - 2009) arranged and played via MIDI on a Yamaha TX81Z rackmount synthesizer, circa 1987. This module features sounds similar to the Yamaha DX series keyboards. It's a digital synth with Eight voice polyphony and 128 preset sounds. The composition was arranged and trimmed to fit within the limitations. I only used the stock sounds built into the unit.
