Grape Solutions’ Pluto is an online synthesizer and digital audio workstation. It’s implemented in a web browser, and based on Microsoft Silverlight.

It offers:

• 16 tracks with 32 voice polyphony plus 6 fx/track
• Granular synthesizer, Karplus-Strong guitar synthesizer or drum-machine per each track
• Highly optimized, multithreaded audio pipeline
• MIDI import/export, WAV export

Pluto is not a commercial app, but is intended to be more of a demonstration of what can be done with Silverlight in a Web browser.

Pluto is processor intensive – it comes with some demo tracks (including Jarre’s Equinox 5), and they pushed the limits of my dual-processor 1.66Ghz machine.

If you give Pluto a try, leave a comment and let me know what you think of it!
