Korg iMS-20 for iPad puts classic synth on your Apple slate

When it comes to delicious, squelchy analog synth noises, Korg are known for having some of the best. Problem is, most of us have neither the funds nor the space for a proper Korg analog synth, and so the company has pushed out its latest iPad app, the Korg iMS-20. A $15.99 download from the iPad App Store [iTunes link], it's a complete virtual recreation of the classic MS-20 complete with a few added extras.

For instance, you don't just get the mono synth, you also get a 16-step analog sequencer, a six-part drum machine and a Kaoss Pad function for more intuitive mangling of the sound. A mixer is included to wire everything up, and there are some virtual patch cables to keep the UI looking authentic.

Once you've come up with some songs you can share them online with SoundCloud (though you'll have to sign up for a free account first). Samples galore here, and the $15.99 price is apparently valid until January 31 2011 after which it will ramp up to $32.99.
