Data glitch every 10 seconds? DatTo CHOP?

General TouchDesigner Discussion

Hey everyone, this one is puzzling to me.

I’m working in 19930: I noticed the glitch actually coincided with the looping of the 10 second timeline in Touch. I even tried unplugging my Arduino/rotary encoder, which was the original source of my data, and still the glitch happened, every 10 seconds. So its not even the Arduino at all it seems.

Now If I change the timeline to 60 frames, the glitch happens every 1 second, etc etc. It definitely follows the loop of the timeline. Perhaps I’m miss configuring to DatTo CHOP? A timeslice setting?

See the .toe here if anyone think they may know where I went wrong. Thank you!

Here’s a video of the anomaly: DatTo Bug? TouchDesigner 19930 - YouTube

I’m not sure what’s happening. I see the same behaviour in latest 2021 official. Seems like the extend right parameter of the DAT to Chop is set to cycle internally - at first sight looks like a bug? @JetXS or @ben can you take a look?

Thanks for the example, this does have to do with the multi-sample range of values and time slicing, the timeline resetting is not kind to time slicing. Asking @rob …

My hack was to simply set the timeline length to 999999999999999999999. :frowning:
