Hi. I just picked one of these up, and noticed that the number one comment people make is that it's not possible to use it outside of the software and drum samples provided. Not strictly true!
Here's a link to my article and script that allow you to give your iED05 USB Drum Kit MIDI capability so you can use it with your sequencers, software synthesizers / samplers and notation programs - http://wibwobweb.com/ied05midi/
