Ultra Full Version is a synthesizer developed by Ultra Audio, built around its proprietary UltraWave™ engine—a hybrid approach that extends wavetable synthesis with elements of sampling and real-time morphing. Available as a VST3, AU plugin, and standalone instrument, it focuses on advanced waveform design, stereo wavetable processing, and dynamic sound shaping. It’s positioned as a modern wavetable synth for detailed sound design, particularly for evolving textures and expressive playback.

Key Takeaway

Ultra is not a traditional wavetable synth focused on preset browsing or quick results. It’s built for shaping complex, evolving sounds at the oscillator level, especially when working with imported audio or hybrid synthesis workflows that blur the line between sampling and synthesis.

UltraWave engine blending wavetable and sampling behavior

At the core is the UltraWave engine, which extends wavetable synthesis by embedding pitch, amplitude, and timing data directly into the waveform.

Instead of switching between discrete samples like a sampler, it morphs continuously between states. Notes played between mapped positions generate hybrid waveforms in real time, which change how transitions feel during performance.

This makes it possible to treat complex material—like vocals or textured recordings—as playable synthesis sources rather than static samples.

Stereo wavetable design with independent channel content

Ultra supports stereo wavetables where left and right channels can contain different waveform data.

This introduces movement directly at the oscillator level, rather than relying entirely on effects or modulation. Subtle differences between channels create width and depth that evolve.

In practice, this reduces the need for post-processing stereo enhancement, since spatial variation is already built into the sound itself.

Multi-sampling mapped across pitch and velocity

Instead of relying on a single wavetable per oscillator, Ultra allows multiple tables to be mapped across pitch and velocity ranges.

The engine interpolates between them, generating blended waveforms dynamically rather than switching layers. This results in smoother transitions and avoids the stepped behavior typical in sample-based instruments.

It also makes dynamic playing more responsive, since velocity changes affect the actual waveform structure rather than just amplitude or filtering.

Advanced audio import for custom wavetable creation

Audio files can be imported and converted into wavetables, with tools for extracting waveform cycles and shaping them into usable synthesis material.

Pitch and amplitude data can also be captured from source material, allowing complex sounds to retain their internal movement when translated into the engine.

This shifts the workflow toward building sounds from raw audio rather than relying solely on factory oscillators or preset libraries.

Five-oscillator architecture with flexible routing and filters

Ultra uses a five-oscillator structure, with multiple engine types available per oscillator, including UltraWave, analog-style, and sampler modes.

Routing is not fixed—oscillators can be sent through different filter types, FX buses, or direct outputs. Dual filters with multiple models expand tonal shaping beyond basic subtractive paths.

This flexibility allows both traditional synthesis structures and more layered, parallel signal flows, depending on how the patch is built.

Integrated sound ecosystem with patch marketplace

A built-in sound library connects to an online ecosystem where patches can be browsed, previewed, and installed directly.

Sound designers can also publish and sell their own content within the platform, turning the instrument into a distribution environment rather than just a preset container.

This extends the lifespan of the synth beyond its factory content, especially as new patches are continuously added.

Hybrid wavetable synthesis focused on evolving and expressive sound design

Ultra operates in a space between wavetable synthesis and sampling, where the emphasis is on how sounds evolve rather than how quickly they can be selected. Building patches requires more input, particularly when designing custom wavetables or mapping multi-sample behavior.

Once configured, it produces movement and variation directly at the source level, which reduces reliance on heavy modulation chains or external processing. The trade-off is a steeper learning curve, balanced by deeper control over how sounds respond and develop over time.

FAQs

What type of synthesizer is Ultra?

Ultra is a wavetable-based synthesizer with a hybrid engine (UltraWave) that blends wavetable synthesis and sampling behavior. It focuses on dynamic waveform generation rather than static oscillator playback.

Does Ultra work in major DAWs?

Yes. It supports VST3 and AU formats and can also run as a standalone application, making it compatible with most modern DAWs on macOS and Windows.

Can Ultra import audio and turn it into wavetables?

Yes. It includes advanced import tools that extract waveform data from audio files and convert them into playable wavetables with additional pitch and amplitude information.

Is Ultra suitable for beginners?

It’s more suited to users comfortable with synthesis and sound design. The flexibility and depth come with a learning curve, especially when working with custom wavetable creation and routing.

How is Ultra different from typical wavetable synths?

Traditional wavetable synths rely on fixed tables and modulation. Ultra’s engine morphs between multiple tables dynamically and incorporates sample-derived data, resulting in more continuous and expressive sound transitions.
