The Dave Smith Sequential OB-6 Keyboard 6-Voice is a dedicated analog synthesizer built for musicians who need authentic 6-voice polyphonic sound generation. If you are searching for dave smith sequential ob 6 keyboard 6 voice alternatives, you might be looking for instruments that offer different key counts, form factors, or specific connectivity options. This synthesizer excels in pure analog tone production but does not function as a traditional 88-key stage piano.

These choices ensure you find a instrument that matches your exact performance requirements.

How these alternatives compare

Nord Piano 6 88-Key Stage Piano

The Nord Piano 6 88-Key Stage Piano replaces analog synthesis with high-fidelity acoustic and electric piano emulation. It features an 88-key triple sensor keybed for precise touch response, which differs significantly from the OB-6’s synth-oriented action. Weighing 55.1 pounds, it is a stationary instrument unsuitable for frequent transport. You gain onboard effects and a dedicated stage piano platform but lose analog sound generation entirely. This model suits pianists who prioritize authentic key feel and piano tones over polyphonic synth capabilities. It is best for fixed setups where portability is not a requirement.

Nord Piano 6 73-Key Stage Piano

The Nord Piano 6 73-Key Stage Piano offers a compact alternative to the OB-6 by providing a triple sensor keybed in a smaller form factor. It weighs 49.1 pounds and measures 49.3 inches in length, making it slightly more manageable than the 88-key version. You trade total key count for portability and precise touch response. Like the 88-key model, it focuses on piano emulation rather than analog synthesis. This instrument is ideal for players who value key feel and onboard effects but need a smaller footprint. It sacrifices the OB-6’s analog character for a focused stage piano experience.
