[sdiy] Audio playback chips as sample players for drums

[Mike Bryant]

10mS is usually quoted as the absolute maximum latency you can accept, but whereas I'm almost tone deaf on pitch I can perceive timing errors far less than 10mS, the 'drummer' in the farm next door driving me mad with his poor timing when I walk by his practice studio.

I've seen a number of these sample/wave/mp3 players that use either Flash memory or SD cards for storing the files. They look tempting to create a sample player module. Has anybody played with these? Is the latency acceptable enough to do drum samples?  How much latency can you have before it becomes noticeable?
Something with a minimum of 8 triggers to kick off  different samples that can be played simultaneously.  I've seen some where you give the files a number, and a trigger can be associated with a numbered file.  With a microcontroller you could have an interface to pick and audition the samples you associate with the triggers.
