This is regarding the "soft clip" option in the Mastering Tool Kit in Roland VS multitrack recorders.
The manual is misleading about the "soft clip" option in the MTK.   The "soft clip" limits the output like a brick wall. The level meters at the output of the MTK will stay well below the maximum. This, however, is not the misleading part.   The software and the appendix-manual lead you to believe the output's "soft clip" is before the output's "level" adjustment.  In fact, the "Soft Clip" is applied after the "Level" adjuster.  The "Soft Clip" actually reduces the overall volume. Adjusting the "Level" adjustment in the output section (of the MTK) won't bring up the level. It will only create distortion.  There is a limiter in the MTK that works quite well and behaves as expected. Use it instead of soft clip.  Initially, it appears you can correct the signal loss by increasing the master fader. This is a bad idea if you are dithering to 16 bits. The master fader needs to stay at 100 because the master fader is still operating at 24 bits. (Dither occurs at the end of the MTK chain.) No processing (volume changes) should be done after dithering.   Simply turn off the soft clip and use the "limiter" section instead. Then the MTK will behave more as expected.
