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.

I should also mention that I am new to this synth. ANY info is useful.

I just recently bought one of these. Sounds great! However I noticed that the arpegiator doesnt seem to be working. Looked at all the settings and I cannot seem to get it to work. Currently looking for a factory reset for all the settings. Maybe even a firmware update. Any clues? Im overwelmed!

Lots of comments on how bad or good this synth sounds. It sounds a lot like an Arp to me. Many of the patches sound very analog. See for yourself as I have about 50 videos posted on youtube of some of the best patches on it!

One of the best synthesizers I've ever used. It has a bunch of cool features, very easy to use, and sounds great. I would recommend it to anybody.

Only problem, the backlight on mine is burned out, and this is pretty common. Even with a burned out backlight I can still use the synth fine and still create sounds and store them, etc. Just keep a flashlight handy.

Also, it does have some quirks, such as DSP overload if you tweak certain settings a certain way, but those problems are few and far between and don't take away from how great of a synth it is. 5/5

The OB-12 is a great-looking synth and like most people I was also attracted to the Oberheim brand name. I owned one of these from 2002-2004. But I was very disappointed with it. The main outputs gave out a huge amount of noise, and so did the phones output. I think there was a digital output too but I have to admit I never tried that. Anyway the noise made the synth unuseable for recording purposes, which was all I was interested in. Maybe it wouldn't be so noticeable in a live setup.
I guess it's possible that I just got a faulty one, or that this was fixed in a later version of the O.S.
