Title: What would cause one repeat ZPSDX "FIXED"
Post by: blearyeyes on July 31, 2014, 04:23:40 AM
Everything is working fine, what would cause a Zero Point Deluxe v1 to have only one repeat when on the first mode setting "analog"?

Does this behavior depend on the PATH switch?

Edit: In other words: Is this first repeat unfiltered? Then maybe you don't get any repeats in the filtered position of the PATH switch because the delayed signal gets lost somewhere in the analog filter path (C32 to C38).

Looks like only one repeat when path is engaged and none when it is off.
All other modes work as expected, that limits it to the analog loop. I guess....

the feedback pot doesn't do anything in analog mode...as expected... I'll have to pull this beast out of the enclosure...
I used a hammer to get it to fit. haha

I built this as my fourth project a while back?...duh!  Totally not a beginners project.
The solder work wasn't up to snuff; cold solder joint.... Re-flowed the rotary switch and all is well.
