[sdiy] Audio playback chips as sample players for drums

[David Huss]

My experience is that the latency with those (DY-T5WL) is poor, definitely unusuable for live drums. I didn't measure but just by feels I expect the latency to be in the order of 200ms. 
  
There might be lower latency modules rhan this one

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.
