Sequential and Tom Oberheim reveal the secret of their collaboration: the 6-voice and completely analog synthesizer OB-6! The keys of the OB-6 are semi-weighted, velocity-sensitive and feature Aftertouch.
The OB-6 is the result of development, the aim of which was to combine the vintage SEM sound with the flexibility of modern technology. This has produced a synthesizer with a sound that sets striking accents and, thanks to full programmability, and provides synth-hearts with adrenaline.
The OB-6 features two separate VCOs (plus Sub Oscillator) per voice and continuously variable waveforms. The OB 6 you have the choice between sawtooth, square and triangle wave. The pulse width is also variable.
Each of the voices may pass through a high-pass, low-pass, band-pass and notch filters. The analog signal is rounded off through a VCA.
Filter Envelopes and VCO 2 used in the X-Mod act as modulation sources. Several buttons can be found on the front panels, that help to activate practical functions with just a single finger.
The double effects section delivers studio quality reverbs and delays. It also allows for a brilliant chorus, plus a redesign by Tom Oberheim of the acclaimed Phaseshifters and ring modulator.
The effects are digital and have a resolution of 48 kHz (24-bit). However, due to the true-bypass, the analog signal is maintained. In addition, the OB-6 has a multimode arpeggiator and polyphonic step sequencer.
Stunning synth. I’d been to two other studios and tried the prophet and the DS OB6 and the OB sounded much better, and analogue. The prophet sounded thin in comparison.
I’m really pleased to have this OB6 and now need to read the manual
