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.

astonishing machine.
this thing is nowhere near easy to program, but if you put in the effort, the reward will be sweet. unlike anything I had in my hands, very unpredictable and trippy and a great piece of kit for experimental stuff.

Knobs(28), wheels(2), pots(25) and buttons(81) are first class,display is da bomb and layout is optimal, it's built like a tank. The OSCs have 3 waveforms each so in fact you have 6 OSCs from which you can choose from plus there is a common section for all OSCs with extra features. Two filters with the configurations and 2 type EQs - limitless opportunities. All timbres are stored in flash and are editable, and all programs contain up to 4 timbres split or in layer- you can make real phat, complex, changing sounds and effects. Sound can be analog and digital as well- skills. 20-40 factory presets are only useful. Ribbon controller is great, effects are cool! Viscount or OB- who cares? It's better soundwise than a Nord or the Jp8000, more flexible, more sexy and cheaper too. Morphing is a great either manually or auto- storeable in every program! I have an ms2k as well and the built quality and pads of the OB12 are better. 4,6 out of 5.

"sound from audio main out is too quiet. can somebody help me ???" yes... you've got to raise the gain in the mixer's channels where you connect the OB12! this will work. synths have different impedance (+4 dBu / -10 dBV etc)...
anyway: my first real synth ever, my favourite one to program. it won't do everything, but it can do a LARGE amount of analog-like and digital sounds. I also squeezed some PPG-like evolving sounds out of it! also some very DX-like evil FM timbres... your programming skills and your imagination are the limits! I don't understand people bashing this synth. maybe they didn't spend more than 10 minutes with the OB12. maybe they don't know how to program synths in creative ways. maybe they only program moog-wanna-be bass and leads and some strings and brasses sounds. this synth can do it, but it's more a synth for experimenting than for copying old synths. can you tell I love it?
