The small club applause was available as an SFX kit.

However, if this is the ONLY thing he needs, why not sample it, and use it in the T2's sampler?

If he is prepared to learn how to get the T2's style and keyboard voices to address the Sc88Pro, there are many good voices and kits in there to mix and match (I wish there was a module T2 to add to my G70!). But if the applause is it, sample it!
