Voice 1 and 39 combined with sustain on is sounding excellent. It is like listening to the radio. Voice 80 and also voice 36  combined with another special voice sounds like a churning orchestra ,excellent sounding.  

still working since 1993, isn't that good? This keyboard can be depended on for reliable use.

I think this was much pricey back in the 90's but today you can have this from ebay for around $75.00!

Very good high quality keyboard that is not professional but that doesn't hold it back.
