ameleon 5000 is an additive synth, featuring resynthesis and sound morphing, which excels at pads and evolving textures and comes with a library of over 800 presets. At its heart is the morph square which allows you to morph between four different instruments at once. You can also use the morph timeline to create rythmic loops, evolving soundscapes and pads. Uniquely, Cameleon comes with a range of preset morph timelines, to make creating new sounds even easier.
