MetaSynth Studio CD for Mac

From Rob Vonk:

Paint with sound, compose with color and light. MetaSynth is the first program to apply the power of advanced computer graphics to the realm of audio. MetaSynth is the only audio software that applies the power of advanced computer graphics to music, synthesis and sound design. MetaSynth combines sampling, wavetable, additive, subtractive, granular, wave shaping and frequency modulation techniques with the world's most intuitive display for visualizing and manipulating audio. MetaSynth lets you paint with sound. It works with audio like a graphics program. Even non-musicians can instantly interpret and use MetaSynth's picture window. Create a vivid tone picture, splashing broad strokes of sound across the screen. Or carefully draw in notes, harmonics and undertones, entire scores, controlling every sonic nuance. Fun to use, not a toy. MetaSynth is a cutting-edge sound transformation engine that allows you to freely mix and match synthesis and signal processing techniques. Start with any synthesized waveform, real world sampled sounds or a combination of the two.
