Re: CGS07 - Gate Sequencer Reset

2017-06-25 by Paul Bower

You mean a kind of lag between the reset event and the clock advancing to step 2 / step 3 etc ?

I’ll check for that - I just tacked the extra cap on the back of the board, so it’s not so much of a faff to try some lower values

The only "issue" having the reset cap to big is that it may prevent a clock pulse from advancing close to when the reset occurred.

Good to hear from you Ken - hope things are good over there

Since that’s all I had, I just put a 47nF cap across the existing 10nF and that did the trick

In case anyone else comes across this, it was a very old board. I could get the gate sequencer to reset from its own 12V step outputs, but not from an LFO that was sending a 0-8.5V squarewave (and certainly not from a variety of things I tried at around the 5V mark)

So all fixed - I can reset on a 4.5V pulse now
I assume that if I get misfiring problems now then I just need to reduce the value of that bridging cap a little ?

Cheers
Paul

I should work that way already. Perhaps increase the size of the 10n reset cap to 47n to let a bigger pulse through.

Hello there,

Just wondering if anyone could recommend a way of modding the reset input to accept +5V instead of +12/13V
Cheers
Paul
