Oberheim OB-12

Move out of the way everyone because the Big-Boys are back in town! Oberheim is back with their first analog-emulation professional synthesizer. This blue beauty is supposed to recreate and emulate the classic sounds and tone of the original Oberheim analog filters. The OB-12 is a 12 voice synth with 4-part physical modeling synthesis. Loads of real-time knobs (22), sliders (24), and buttons (33) with a traditional layout give you fast hands-on access and control of most parameters. Extra hands-on goodies include a ribbon controller, pitch bend and modulation wheel.

Aside from great analog sounds, the OB-12 has an amazing set of hi-tech features! The OB-12 features a high quality LCD display that actually draws out all of the parameters you are changing. There are on board 5-band graphic & parametric EQ, ADSR's with delay time and double decay. An addictive Motion Recorder and manual or auto oscillator morphing for animated sounds or effects. Phrase Recorders and Arpeggiators with Independent tempo controls and 5 dedicated buttons are on-board with plenty of features and are MIDI syncable. There is also an extensive effects section that give you reverbs, delays, chorus and lots of overdrive algorithms. You'll also find digital SPDIF outputs, analog outputs, and MIDI in/out and thru.

Fantastic Synth. Oops! I love instruments that engage unpopular reviews that way the masses keep away. The ob-12 is a noise machine and one of the finest. It's unpredictabilty is what makes this under rated beast so superb. I have Moog. Roland. Kawai and Dave Smith and the sound generators on this stand up beautifully to them all. Yes I'm an experimental/Avant musician and not much into conventional merlody. For that go buy a piano.

This is a hard synth to explain, not an oberheim... not analog at all.. hard to master.. Hard to ever get the eq mixed right so it sounds good... makes some werid crazy squeels and blips and stuff.. had one since new.. bought it cause i thought it was going to be like an super xpander or matrix 12 but digital... its not quite that but its something else.. i still have mine... i would say that you should def not buy this as your main synth... but it can make some unique sounds
