“In working order, I have tested the EXT-IN using another synth (yamaha DX100 also for sale, see other items) the EXT-IN is a cool feature of this synth and allows for the filler to be used on an external sound source and then the various knobs to be tweaked in real time to trigger some amazing sounds.
This synth pre-dates midi but does have the CV out which can be used with a MIDI convertor.
I have tested all the Knobs and switches, all do their job, a couple of crackles on the VCA intial Level and the VCF switch, but all the main switches/knobs like the Cut off Freq, Resonance work just fine.” Link
“It was taken in on trade and the keyboard is in overall good condition. I plugged it in and tried all of the keys and they all work. The high F and the keys to the right of it need to be adjusted. If you look in picture 3 the high F is at a slight angle and the other keys feel a little tight. They all went down and returned the way they are supposed to.
All of the knobs seem to work good. Lots of good sounds.” Link
