UltraWave is Ultra’s patented wavetable synthesis engine.

Why is it cool?

It provides several enhancements over traditional wavetable synthesis:

• Multi Sampling
• Stereo wavetables
• The ability to create realistic playback of complex sounds - such as vocals - in a wavetable engine
• Cross fading / morphing between samples
• A powerful import engine to convert Samples to Wavetables

Think of UltraWave as the cross between a Sampler and a Wavetable synth.

What is it for?

UltraWave does all of the things that a Wavetable does, but also allows:

• Creating instruments that blend between two audio samples, rather than switching
• Wavetable cycle level warping to Sample type sounds
• Time-stretched or LFO playback within a sample
• Analog synth modelling

How it works

When you play a note, the UltraWave engine will:

• Play a short Attack transient sample
• Start playing cycles from a wavetable
• The pitch of the cycles is controlled by the note you play, and a pitch curve
• The volume of the cycles is controlled by an amp curve

The combination of an Attack sample, pitch curve, amp curve and wavetable is called a Sound.

Sounds can be stereo, and have different content in the left and right channels.

Multiple Sounds

You can place multiple Sounds on different notes and at different velocities in the UltraWave map.

Sounds are represented by blue squares in the map.

When you play a note, the engine will play back a hybrid sound that is a combination the closest 4 Sounds in the map.

So unlike a sampler, this allows you to have smooth transition notes between two samples.
