Fixed!
In stead of a lm358 I had put a tl072 for clock input.
I changed it to a lm358 and it works perfectly
I never noticed an opamp changing spec over time but it seems to have changed. Weird!
All good in the hood!

Subject: [cgs_synth] CGS 07My CGS 07 gate sequencer which has been working so well for a decade has suddenly become faulty
Its as if all outputs are stuck in full position
would that be a faulty 4081 in the output buffers?
