Just did some more testing and found that:

Step Output #4 fires when the sequencer is on step #3 and again on step #4

Step Output #8 fires when the sequencer is on step #7 and again on step #8

All the other Step Outputs (1, 2, 3, 5, 6, 7) fire as they should.

Something related to the 3rd bit output of the 4016 maybe?

Subject: [cgs_synth] Sequential Switch - outputs double triggering

I fired up a Sequential Switch (the V1 model if that matters) that I built long ago.


I was playing with plugging the SeqSw step outputs (P1, P2, etc) to the Clock IN on my newly built Gate Sequencer and noticed that while steps 1, 2 & 3 advance the Gate Seq as you would expect, step 4 output advances the Gate Seq *2* steps, as if it is double-triggering.


Any suggestions on what I might look for on the SeqSw that would cause the P4 output to double-trigger? I have it configured as a basic 8 step sequencer (no inputs on the steps). And I don't have a scope [☹]
