I'm having a problem figuring out what is wrong with the animator. It seems to be "working" and I've checked the resistors and caps a bunch of times.

Here is what it sounds like ... about 10 seconds from slowest to fastest. Nothing mixed in. This is just saw through channel 1. It sounds identical on both, and the normal connection is working properly between 1 and 2.

Any ideas, just from the sound what could be wrong? Like I said, I checked and tested the resistors and made sure I had correct caps. Not sure what else to check. It calibrated easily enough.

Did you try to readjust the trimmers ?

Yes, the saw shows up fine on the scope when trimmed +5/-5. And, it actually sounds perfect when grounding the mod input. I think there is something wrong with the mod interaction. It doesn't matter if it is internal or external, but it acts more like an extreme tremolo.

I included the sound example just to make sure it's easy to understand what is coming out. But if you listen to the initial 5 or 10 seconds, that is the slowest setting on Input/Output 1. If you listen close you can hear the almost square wave Hi/Lo.

EDIT: And thank you very much for taking the time to respond.

I forgot to come back and say I figured out that my problem was me and a proper patch. The animator is working great. Thank you!
