There are several ergonomics problems i've noticed. First, the fact that it is not possible to load a preset from the app to the plug-in is really time consuming. Saving any preset on the plug-in is impossible (only the calibration profile can be loaded). If you monitor with several pairs of loudspeakers, it's a big problem... Other detail : It would be amazing if the plug-in window could have an adjustable size. The custom target mode is a very good idea, but it's a shame that the EQ that we can manually do is affected by the dry/wet mix and not effective outside the frequency range. If I hadn't so many acoustic problems because of my little room, I wouldn't have bought Sound ID.
