Good morning, afternoon, or evening, as the case may be...

I would like to put some musical excerpts on a page of my music website. I`d like to have clickable links that would stream good quality piano sound when the user clicks it- maybe 30 secs to 1 min. samples. I`ve got a digital piano with midi. Does anyone know a good site that explains step by step how to do this, or what is the best way to do this, and what I would need? I`ve been reading up about it (embedding, wav files, real audio, etc.), but I haven`t found quite the answers I`m looking for...

Also, how does one make/store midi files on a computer?

Any help appreciated
