Yamaha CS-50
The CS-50 was released just ahead of its famous big brothers, the CS-60 and CS-80. The CS-50 looks like a scaled-down version of the monstrous CS-80, and it is! This will benefit those who crave the famous classic Yamaha synth sound without the struggle of lugging around the 215 pound CS-80! The CS-50 weighs in at about 100 pounds. The CS-50 is also just 4-voice polyphonic, and lacks the quality weighted 61-note keyboard of the CS-80. The CS-50 has just a 49-note standard keyboard. It does feature pressure (aftertouch) sensitivity route-able to several destinations, however.
The CS-50's sound is unmistakably related to other classic CS-series synthesizers. At just four voices with one osc. per voice and lacking warm filters (at just 12dB/oct) the CS-50's sound can be thin. There are 13 preset sounds of various instruments and synth sounds but, unfortunately, no on-board memory storage for your edited presets. At its low street price, the CS-50 makes a great way to get your hands on these classic sounds without going broke! It's too bad their tuning is just as unstable as the other CS-series synths. It's housed in a built-in travel-case like the other (big) CS-synths. It's been used by Men Without Hats and Herbie Hancock.

plug carefully, only by mixer and/or CV intrerface.
Today the risk to lose old synths is high( and expensive... )
Patrick kill your friend!!!
If the guitar pedal was active ( with battery) a wrong voltage imput could burn some IC. If passive maybe made a short-circuit.
DONT plug any vintage synth IN or OUT with active devices, also pre!
Or experiment with unknow items.

According to Duncan himself he flew the first CS-80 from Japan into England and Yamaha had lent him a CS-50 to use until it arrived.
