Sequential OB-6 Synthesizer Module

A sleek, compact counterpart of the classic keyboard version, the Sequential OB-6 Synthesizer Desktop Module is a hands-on module that delivers the same effortless workflow. A once in a lifetime collab between Dave Smith and Tom Oberheim, the OB-6 is bursting with a warm immersive tone that can still easily fit into your backpack.

Boasting all the features and extensive connectivity that the keyboard version of the synth includes, the OB-6 Synth Module is perfect for producers limited on space in their studio but looking to expand their sound collection.

Key Features:

Mighty Analogue Sound: Championing signature bold Tom Oberheim tonality, the OB-6 offers true voltage oscillators, a 2-pole filter and amplifiers. However, it also adds latter-day features such as studio-quality effects, a polyphonic step sequencer, an arpeggiator and more.

Compact Design: Like all desktop modules, the OB-6 is impressively portable, making it the perfect choice for producers always on the go. Don't be mistaken though, as the OB-6 doesn't lack in performance or sound.

Dual Effects: Bursting with a vast selection of studio-quality effects such as reverbs, delays, chorus, flangers and much more. The OB-6 also includes Tom's original phase shifter and ring modulator for a truly signature sound.

Sequential OB-6 Synthesizer Module Specifications:
