Unfortunately my internet is not working that well (and neither is the power cable to the iPad...), so I haven't been able to test it myself just yet...
But it surely looks to have some nice enhancements, as found in the iTunes page for Korg Gadget:
What's New in Version 3.0.0
• “Recife” - A new powerful drum gadget with 16 pads.
• Supports music sharing service "Allihoopa". http://allihoopa.com/
• Supports exporting plug-in data with Ableton Live Export.
• Supports audio document manager “AudioShare”.
• Other improvements have been made to enhance stability.
If you have Korg Gadget, be sure to update!
If you don't and have been wanting it for a while, you are lucky because Korg has cut the price in 50%!
Have you tested this new version?
If so, just leave your feedback as a comment ;)
