analogue drum moduels

[Sam Hargreaves]

hello synth-diy
My names Sam i'm a third year student at Derby university 
England. For my third year project i'm researching and hopeing to 
build an analogue drum synth moduel. the research is going well i 
have plenty of circuits but i'm interested to find out how people 
make there different drum sounds so i can decide what to put into 
my moduel??

i'm first going to concentrate on the snare drum so if any one has 
any idears or opinions they would be greatfully recieved.
thanks sam
