2 DCO (12 voices), 3 LFO, SSM (2044 filter/2056 vca) goodness.

dk600“SIEL DK600 Analog Synthesizer Working Great and Sounds Awesome! See Pics & Desc! Up for sale today is my personal Siel DK600. I do a lot of buying and reselling but I have owned this one since around 1994! It was dead when I received it, but it turned out just to be the battery. Fortunately, this keyboard never suffered serious corrosion as I was able to replace the battery long before there were any major issues. I’ve had this keyboard in the closet for about 10 years and just don’t use it too much due to DAW plugins so I have reluctantly decided to let it go. The battery was once again dead, so I just put a fresh one in a few weeks ago. Also, I reprogrammed it using a sysex dump someone made on the Internet from an Opera 6 and it’s working great! Does everything work? Well, I do not know for sure. I know the tape interface which is used to save sounds never really seemed to restore the sounds correctly, but the sysex dump does! The controls for the DCO, LFO, etc are responsive and you can save and load sounds using the keyboard. However, there may be advanced functions I am missing. Anyone who is familiar with these keyboards know they are finicky and frankly, was not designed for travelling in my opinion. Since I have owned it, I moved to from Texas to Washington state, and back to Texas. Each time, I had to crack it open and reseat some of the connectors. When changing the battery, I attempted to clean them all as well as I could. What am I saying? It’s possible something could shift when I send it, but the worst case will be opening it up, and pushing all of the connectors tight. Hopefully, they are clean enough to make it. We package everything VERY well, and will take every precaution we can to keep it safe! ” Click here to visit listing on eBay

dk600 ” SIEL DK600 Analog Synthesizer. Oscillators and keys and controls seem to be functional and it produces interesting synthesizer sounds, very clean condition, nothing obviously physically broken and all knobs and rockers vary the sound and appear to be functional. Was purchased by a friend and traded to me for my studio in exchange for other items and services. Not much interest in a synth since we record blues and rock.

It has two programs, 11 and 12 loaded, and entering other numbers does not produce sound. Contact me if you have specific questions I will try to answer. I am willing to do a phone or FaceTime to discuss the operation of the unit.” Click here to visit listing on eBay
