[sdiy] Roland drum trigger spec's

[nss at hevanet.com]

Hi eveyone,
A couple of months ago I made a copy of the 808's tom/conga section.
They are pretty much straight clones, the only difference being I used a
tl082 instead of original. But they all had a problem. The pink noise
would not make it to the output. I copied the original noise generator,
and it seemed to be putting out the correct voltage, but no mater what I
played with it still would not work right.
	Then I remembered someone saying that the Roland trigger is suposed to
be a 10ms pulse and some sounds would not work right if this was varied.
I am using a PAIA midi-cv that puts out a 5ms pulse. Could this be my
problem????

Anyone with experience on this?
Could the circuit be modified to work with 5ms?

I put up the schm of the section I copied if someone would take a look:

Thanks for any info anyone can share!
My tom clones will thank you too, as I already butcherd one of them
trying to get it to work!
