Master Class: DSI OB-6

It’s no exaggeration to say that Dave Smith Instruments’ OB-6—a true collaboration with Tom Oberheim—has quickly become one of the most sought-after analog polysynths of the 21st century. By combining elements of Smith’s own Prophet 6 with the filter topology of the Oberheim SEM, the OB-6 is capable of textures that are unlike any other analog poly to date.

For this Master Class, I won’t be rehashing the generalities of analog synthesis. Instead, the focus is on programming tricks and techniques that highlight the possibilities lurking within the OB- 6. It’s also worth noting that several of the tricks in this Master Class also apply to the Prophet 6, thanks to its similar architecture, so proud owners of that synth may find a few tidbits they can use as well.


Pro Tip: Emulating Chaos

Among the main characteristics of true analog instruments are the subtle idiosyncrasies that occur at the circuit level. While many modern softsynths attempt to re-create waveforms and filter curves accurately, there is a certain richness that comes with the variations that occur in real-world instruments. Even Dave Smith Instruments includes a “slop” parameter for the Prophet 08’s DCOs to re-create these artifacts.

In this tutorial, we’ll look at ways to use common tools, such as noise modulation and high-speed LFOs, to add low-level indeterminacy to your oscillators and filters.
