As Bob O. mentioned, you can use POWR dither (available in the preferences) in Samplitude. I don’t know if it will apply across the board and include the monitor output. You’re going to have to do some clever sleuthing to determine if the monitor output is dithered. For example, feed AES/EBU out and back in and record it and you’ll know by examining the return from the monitor with the Bitter plugin.
