Sequential OB-6 Synthesizer Module Overview
The Desktop version of Sequential’s OB-6 condenses the unmistakably rich sound & tactile interface into a highly portable & compact package. All the features, including the extensive connectivity and studio-quality effects, are here!
Compact Design
The OB-6 Desktop is as tactile and immediate as the Keyboard version, with the same easy workflow and array of hands-on controls. Internally the OB-6 Desktop is identical to the Keyboard version, packing that warm, encompassing sound into a module that you can fit into a backpack. Plus, all the connectivity options are here (including the full MIDI I/O and USB MIDI) so integrating the OB-6 Desktop into your existing setup couldn’t be easier.
The OB-6 Desktop’s size makes it an ideal companion to your favourite controller, whether that’s a fully-weighted 88 key behemoth or a miniature sequencer. If you like to forgo controllers altogether, this version of the OB-6 easily fits onto a desk and can be sequenced from your DAW.
If you need an all-in-one solution that’s ready for the stage, you may prefer the OB-6 Keyboard, which boasts a slick Fatar keybed with velocity-sensitivity and aftertouch.
Poly Chain
Whilst the OB-6 Desktop works brilliantly as a standalone instrument, it’s even better when used in tandem with the Keyboard version. When put together, you can layer two different patches or use the Poly Chain feature to double the polyphony. Poly Chain is perfect for when you want to pull off ethereal, evolving pads with long releases and thick two-handed chords.
The OB-6 Desktop is a fantastic solution if you want to integrate it into an existing module-based rig, have a controller keyboard that you prefer to use or need to conserve space in your studio. Plus, if you already own an OB-6 and require additional voices, the Desktop version is a neat way to extend its polyphony via the Poly Chain feature.
