Sampler, Sequencer or PC Software.

[apache_sim]

Hi,
I would like some advice on a work related task. I train aircrew using a flight simulator and often feel that realism could be improved with some background sounds, played over the intercom.

I would like to have the ability to play a sound without having to select it from a menu (itunes for example) and wait for the file to load. Is this the kind of thing a sampler or sequencer does? Can I store the sound bytes in memory and have them play instantly, even palying multiple sounds at once.

Is it possible to loop sounds and then play shorter sounds on top?

I hope this is not too vague a question?

Thanks for any help....
