Free Download DiscoDSP - OB-Xd 3 v3.17.0 for WiN

OB-Xd 3 reproduces the legendary sound of the Oberheim OB-X and takes it to a new level. Combine up to 16 voices per note to create massive pads and screaming solos, play complex chords without stealing voices, and enjoy exceptional CPU efficiency. From warm vintage bass to modern supersaw textures, OB-Xd reproduces the rich analog sound that made the OB-X legendary, but now with the power and flexibility demanded by modern production.

The OB-Xd 3 brings the classic OB-X sound into modern production, complementing it with new capabilities.

The multi-mode filter smoothly transitions from bright highs to deep lows, while the self-oscillation function creates piercing, resonant sounds. Shape your envelopes—from smooth, shifting textures to sharp, aggressive attacks. Layer up to 16 detuned voices on each note for a rich, supersaw-style sound, or maintain a classic sound with subtle analog breadth.

An intelligent preset browser lets you instantly find the right instrument across your entire library. Bidirectional MIDI support allows for manual control with hardware controllers. Microtuning support (MTS-ESP) provides access to alternative scales and tuning systems for experimental sound design.

Like the original OB-X, this synth has no built-in effects, making it ideal for use as a base for your favorite reverb, chorus, and delay processors.

The free version includes Standalone, AU, VST2, and VST3 for personal projects. The registered version provides improved audio quality (up to 4x oversampling), commercial licensing1, Pro Tools (AAX) and LV2 support, and direct technical support.

What’s new in OB-Xd 3

Enhanced preset search system: Version 3.10 introduces a new search feature that recursively scans all preset folders on your drive with intelligent duplicate detection. Instantly search your entire preset library with intelligent indexing that handles duplicate preset names, displaying “(1)”, “(2)”, and more. Navigate search results using a convenient index view.

Built-in SIMD optimizations, automatically detected at runtime, ensure optimal performance on both Intel (AVX2) and ARM (NEON) processors. Cross-platform efficiency without compromise.

Unlock bidirectional MIDI control: now with MIDI output for full bidirectional communication. Mirror MIDI commands from XML templates or create your own custom settings with MIDI Learn. When MIDI output is enabled, it sends CC commands to channel 1 (for all channels) or to the selected channel. Ideal for controllers like the TouchOSC or SFC-OB template, it expands your control and creativity.

New Unison Voices: Unison mode supports polyphonic behavior, allowing you to play rich chords with multiple voices per note.

The number of voices in polyphony determines how many notes can be played simultaneously, while the number of voices in unison determines how many voices overlap a single note (the so-called “thickness” of the sound). You can choose from 1 to 16 voices, with each additional voice adding more complexity and depth to the sound.

Play 4-8-note chords on the massive pads, using 2-4 layered voices, or set the polyphony to 1 voice for classic monophonic unison. For best results, use this setting with the Spread knob set to half or higher to clearly distinguish the layered voices. This setting is ideal for enhancing pads, leads, and bass parts, adding a thicker, more spacious character to the sound.

Includes a self-oscillation function, adjustable filter roll-off, and adjustable filter envelope shape, providing greater control and variety in filtering your sound.

Self-Oscillation: The 12 dB filter now self-oscillates at high resonant levels.
Filter Rolloff Control: The new FLT CMP knob in the Voices section affects the rolloff scaling.
Adjustable Filter Envelope Shape: A combination of exponential and linear shapes for attack.
Filter Envelope Inversion: A new button inverts the filter envelope output.
