For over ten years, our sister magazine Computer Music has been giving you music making software that you can use in your studio. Now it's entered the mobile marketplace and is offering you a free tune-crafting app for your iPhone or iPod touch.

Computer Music: Make Music Now, Volume 1 (Dub) is available now from Apple's App Store. This gives you a collection of sampled loops to manipulate and remix via an intuitive touch-controlled six-track audio sequencer.

Themed apps Volume 2 (Hip Hop) and Volume 3 (Trance) are also available, featuring the same intuitive interface but different built-in samples.

Operation of the app is easy: simply drag your chosen sounds onto the arrange page, then resize, copy, layer and mix them to create your own track. If you want to edit the loops themselves, you can use the innovative Clip Masher to slice and rearrange them as you see fit.
