iZotope adjusted his very attractive drum software, iDrum to work on iPhone - you can buy it at the AppStore for five USD only. We did it so, and had a good time jamming with it as you can see in our video - just play it, you can learn about using the editor, tempo setting, volume and panorama setting, and playing it manually. The software is extremely useful - perhaps the most usable drum editor ever -, and the sound quality is really fine. They have two versions now: Club Edition and Hip Hop; iZotope promises more in the near future. The iPhone version is file compatible with the Windows and Mac versions so you can tweak your rhythms edited on the phone for professional use.

Mixxx is a very nice and free software for the laptop DJ which runs on three platforms: Windows, Mac and Linux. And that's not the full story: it is developed with a real open source effort, and they did almost all the important functions we got used to in the expensive packages: plays mp3, OGG, WAV, FLAC, has real time stretch and BPM detection, supports numerous hardware controllers natively, supports multi-channel sound devices, has multiple skins, uses on multi-core CPUs, the maximal audio resolution is 24/96, crossfader's envelope is selectable - just to name some. Get it here.
