Uploading additional sounds to X5D

[LeeWheatley]

Hi

Excuse the question, but is it possible to upload different sounds to a X5D? I know its an old school synth, but the sounds in many ways arent old school enough. I'm looking for synth sounds that you would get on 'Theme for great cities' by Simple Minds, but the sounds on the X5D seem more appropriate to a school assembly.

If I can't get those sounds on a X5D, what should i go for (keeping a tight budget in mind)?

Many thanks
