Music recording within the primary school setting

I have been recording music for many years now using programs such as 'logic' and 'protools', whilst these are excellent for adult use their usage is too complex for children. I have encountered some programs in schools such as 'super-duper-music-looper' which is a program which enables children to construct songs using pre-recorded samples. I have not really seen many programs which allow children to construct their own compositions past just simply recording a live performance. As this is a growing area of interest for older children and adults due to technological advances and availability I believe it has a solid place in the classroom setting. Any-one know of any programs thay have used/heard of or any opinion on the matter?
