When I bought my SY77, among the patches in the "Internal" section of the synth was something called "LEXUS." The lower part of the keyboard played synth-strings, while the upper part played a trombone. If you held the trombone note long enough, a violin/generic string voice would come in a fifth above, up one or two octaves (for example, hold in a C on the trombone, the string would come in on a G). I think the string may have faded in as well---it started faint and got a bit louder. I saved the voice bank to a formatted floppy, but now the synth can't read that particular floppy (it had read it before I'm pretty sure, and it still reads others quite well).
My questions: Does anyone recognize this patch from an SY77 disc? From another synthesizer? How would I go about recreating it on my SY77? What if I had a vector synth like a Korg Wavestation? Would that make it easier? Has anyone ever programmed something similar?
