-2dB volume difference when recording between donuts

EnergyCrush

Is there a known behavior in Loopy Pro where when recording from one donut directly to another with no effects and faders at unity that the donut being recorded into is -2dB than the source?

I was seeing this consistently yesterday while doing some testing with all faders (audio input, colors, and busses) at 0, where I had recorded into a couple of donuts, one through an audio input with an effects chain pre-fader and another with no effects. I then recorded directly from the initial donut recorded with no effects into another, and then again to a different donut but this time through a bus with effects.

In each case the resulting volume in the target donut was -2dB. This appears to be additive as well - whether recording or just metering the destination, so when going from a second donut I'd just recorded into that was then -2dB in volume, and then routing that to the bus with effects, it was then -4dB when metered at the input.

Is this expected behavior?

I have never encountered that. I would be interested in seeing a demonstration and a test project.

If you start with Loopy’s default project and restore defaults does it happen?

I just recorded a 0db signal to orange resampked orange to yellow then yellow to green… all the to magenta. The magenta clip was still precisely 0db

Thanks @espiegel123 - I'll try with a default project tonight and see what happens. It's not end of the world stuff, and seems likely something I did to figure out.
