The OB-Xd already comes with a huge range of very comprehensive and versatile presets, which showcase its sonic capabilities very well. Now that we understand more about the background of this powerful, analogue-modelling synth, and how it works, let’s take a look at some presets and figure out how they're put together. MASTER controls the synth's output volume, while FINE and COARSE enables you to alter the synth's pitch by varying increments. Lastly, we come to the Master section, which is largely self-explanatory. Once you have a sound designed, play multiple, held notes in each mode you’ll quickly ascertain precisely what’s happening in each LEGATO MODE. The simplest way to better understand these is to create a 1-voice sound that has a prominent FILTER and AMP ENV (which both contain fairly low “sustain” levels).

Retrigger (“Retrig”) - Retriggers all envelopes.

Keep Amplitude Envelope - Keeps held notes at the AMP “sustain” level, but allows the FILTER ENV to retrigger, cycling through its “attack” and “decay”.

Keep Filter Envelope - This mode keeps the FILTER ENVELOPE at its “sustain” levels, but allows the AMP ENV to retrigger, cycling through its “attack” and “decay”.

Keep All - This mode keeps both the FILTER and AMP envelopes at their respective “sustain” levels.

LEGATO MODE concerns how the envelopes behave when multiple notes are played/held which exceed the number of voices available. The OB-Xd is also a “low-note” priority synth by default, however the VAM (Voice Allocation Mode) button switches the note-priority to “last-played” (which is more common on modern synths and will probably feel more intuitive to the average player). it prioritised the lowest note played if/when the number of notes being played exceeded the number of voices the synthesiser could produce. The original OB-X was a “low-note” priority synthesiser. These two features need a little more explanation! Let’s begin with VAM. The MIXER section is fairly self-explanatory, providing volume controls for both OSC as well as a third, NOISE OSC.

BRIGHT AMT - Adjusts the brightness of the upper harmonics.

SYNC - Synchronises the +/- oscillations of both OSC1 and OSC2 resulting in a narrower, more precise tone.

STEP - Switches the OSC tuning dials from continuous to stepped (exact pitches).

XMOD (cross-modulation) - Modulates OSC1 according to (the tuning and amplitude of) OSC2 - great for chorus-like modulating effects and/or FM-style grittiness.

When neither sawtooth or pulse is selected, the OSC produces a triangle wave. There are four OSC shapes: triangle, sawtooth and pulse (with adjustable pulse width - PW), and a ramped pulse-wave, which is achieved by selecting both sawtooth and pulse options combined. This draws the user’s attention first and foremost to manipulating each oscillator’s individual fine tuning (spanning four octaves!), invoking all manner of narrow/loose unsynchronised unison, invoking thickening, chorus-like effects, tonal intervals, or even dissonant textures and soundscapes. With that in mind, like a bold statement of intent on the designers’ part, the dials at the very top of the OSC section (which one might intuitively assume to be volume/loudness of each OSC) are actually tuning/pitch.

OB Xd 2.0 was originally posted as a free download from the online music production forum KVR Audio in 2013, until discoDSP – known for the Nord Lead-emulating Discovery synthesizer – gained the rights to update and improve the OB-X software series a few years after its discontinuation.ĭownload the OBX-d 2.0 synthesizer for free here, or pay a $49 donation as support to build future versions of the software.It’s arguable that a great deal of the OB-X’s tonal philosophy stems from the relationship between the two primary oscillators (as opposed to filter characteristics). Other features include an HiDPI mode for retina display monitors and a sleek, dark redesign, giving the OB-Xd 2.0 close resemblance to the classic look of the original Oberheim line.

Additionally, OB-Xd 2.0 is also the first version in the series to have full compatibility with Linux and MacOS, MIDI CC support for controllers, support for Apple Audio Unit (AU), VST2 and VST3 environments. The synth features a new filtering system, with five cutoff settings across 12dB and 24dB modes. The OB-Xd 2.0’s overall sound and behavior mimic the OB-X, OB-Xa and Ob8 synthesizers manufactured from 1979-1981 by Oberheim Electronics, with more modern features included in the virtual package. Renowned soft-synth developer discoDSP has released an overhauled version of their classic analogue-inspired polyphonic virtual synthesizer.
