2 Things needed for Pro L and a bug
Two things are needed to make the Pro-L really useful: The first is a way of compensating the output level back to unity as gain is added at the input. This would allow the engineer to listen to the transient limiting without getting hyped by the gain addition. After determining that the track was crushed enough, compensation could be switched off and final level adjusted.
Secondly, the 5ms look-ahead is too short. 20-50 ms would be useful, and it would also help if it could be locked to attack time.
The Bug: 1x, 2x, 4x Over-sampled modes do not seem to get saved with the preset.

Hold down the Alt key to compensate the output gain.
The oversampling mode (and other output settings) are saved with presets, but by default they are not loaded. We did this so you can try presets without changing your output settings.
You can control this with the lock icon next to the presets button.
