Pro L2 - Metering in bypass (zero latency)
At the moment Pro-L 2 will always introduce some latency. The transparent algorithm introduces the least amount of latency (about 476 samples) which amounts to +/- 11 ms. I think this will be on the edge of annoying while playing a synth.
We might do a dedicated metering plug-in in the future. However, we have many projects work working on and at the moment its not very high on our priority list.
If you have any more questions, just let us know!

It would be very useful if the Pro L2 meters could still be used while the plugin bypass is enabled. I often use the meters (e.g. LUFS, K-system) but find the latency annoying when recording or playing synths etc.
