Assistive Technology, Help with software Options

[jamacal]

I don't know whether this is the right place to post this mail but I hope someone can help.

I work with a large group of young people all suffering from Cerebral Palsy in trying to involve them in music creation using the Macs (iMacs) at our disposal. I am having problems finding easy to use software for these youngsters who have pretty sever phisical disabilities. - There seems to be a some in PC format but thios is not what we are looking for.

Any help would be very much appreciated.

Thank you
