Okay... Cliff and I talked about this and the mix-law for the Looper is incorrect in the current firmware. It should be set to linear mode and it's set to power mode. So if we change it to linear mode it addresses the issue bakerman mentioned above about how the Looper only needs to be at +3dB to match the dry level (instead of +6dB).
However, this makes no difference to when the Looper is set to 100% mix. This will only affect the level of the wet signal when the mix is set to something less than 100%.
