The OB12 - one of the most underestimated synths ever built


I don't quite understand why the Oberheim OB12 - which actually has been built by Viscount in Italy, is such an underestimated synth. In fact it boasts many great features and is almost as versatile as a modular system - without the patch chords of course! The OB12 is an Virtual Analog Synth and was built around 2000. At that time it cost 3.300 DM / 1650€. Nowadays you can get an OB12 well below 1.000€ and believe me it is worth every Cent you pay for it. For endless joy of editing the OB12 boasts 28 rotary Pots - not the endless rubbish of modern synths, but real pots! Further more there are 25 Sliders and 87 Buttons! Almost every parameter can be influenced on the front panel and the rest can be edited via the large graphical display. To tweak the sounds of this synth is real fun!
