Now that Apple has opened up application development for the iPhone and iTouch, music applications are starting to popup making the iPhone and iTouch potential choices for mobile music making.
One such application is the new iDrum for iPhone. It's sold in two editions, Hip Hop, and Club. "Each edition includes 20 unique kits made up of dozens of patterns and samples!" Each edition is only $4.99 and is available on the app store. The YouTube video above gives you a good sense of how the application works.
Probably the coolest thing about iDrum for iPhone is that it integrates with the iZotope's iDrum for the PC or Mac so you can share samples and take kits on the road.
Here is a list of features from the iZotope web site.
Customize patterns to create your own unique beats
Includes extensive library of amazing sounds
Take control of the rhythm of every drum sound and sample
Tap the touch screen to play and record your own musical patterns
Easily turn your beats into ringtones for your iPhone (requires free iDrum Ringtone Sync application for your Mac or PC.)
One of the most interesting new features of FL Studio 8 was the introduction Slicex. According to Image Line, the makers of FL Studio, "Slicex uses advanced beat detection algorithms to slice song/percussion samples into pieces and make them independently playable from the Piano roll or controller."
Image Line has made this tool available as a Stand-alone VSTi so you can run the tool within your favorite host.
I don't really see a need for this plugin for Ableton users considering we have slicing with drum racks, but this might be just the ticket if your using a host that doesn't have built-in slicing.
They are selling Slicex for $99 but it's currently on sale for $79.
