Drum Trigger Signals

[Daniel Gendreau]

I am preparing to DIY some analog drum tone circuits and I had a couple of
questions before I jump into it.

Can someone tell me what they know about drum trigger signals? From what I
know, its a short pulse signal. I am wondering about how long and what
voltage should the pulse be etc.

Specifically, the 808 BD circuit I am looking at has inputs for a trigger
and an accent signal...
Since I dont have the luxury of owning an 808, I cant scope these signals to
see how they are formatted.

I understand that a lot of this is depends on the drum circuit, but any info
would be appreciated.

Thanks,
