Debugging Gate Sequencer

2007-07-28 by The Alison Project

I built my Gate Sequencer yesterday and I am having a few problems with it, in Loop mode everything loop wise is working correctly.

My reset jack will reset with a gate of approx 10V, the 5V gate outs of say my Sequential Swicth will not reset the module.

In Hold mode it is not working correctly, with a sequence of 8 steps when I change it to Hold mode it will just loop between 2-8, and as I change sequence length it will loop between smaller amounts... Every now and than when I change the sequence length it will work correctly for a second.

I have tried using a 100k and 1M resistor from the reset input to ground like the webpage says with no luck.

I am using a LM358 on the main board, I tried a few TL072cp and I cannot get the 4017 to clock at all with the TL072.

I've swapped out the 4017 for another althou all I have on hand is CD4017BE.

I just ordered these boards so they are the latest revisions....

Anyone have any ideas???
