Hi everybody, I've been sarching in this forum (and google) trying to find something helpful but I had no luck, so I hope someone here could help me... cause I'm completly new in Android world.

I'm trying to make a simple "Piano -like" app, so I can press a button and a sound will be playing as long as I'm pressing it. I would also like to record in a text file what buttons I've been presing and how much time (just similar to midi format), so I could reproduce it later.

The question is: what media resource should I use? I should record the "plain sounds" in some kind of music format (one archive for each sound ) and then call them using soundpool? There's no other more optimized option... 'cause I don't like the sound of what I've been thinking of...specially if I want to make a composer mode and deal with time.

Thanks and sorry for my poor English...Greetings from Spain South Europe

I think in your case better to use AudioTrack and own mixer.

Thanks for your answer Marco, can you explain me, why this solution is better than using soundpool? Perhaps you could give me an example?

SoundPool has a memory limitation (for example on G1 about 1M), so if you try to play more than 7 seconds sample you got an error.
