Hi! I just found out how Flat Volume works and I'd put a reference level slider above the streams. So you change it and there would be no confusion why suddnly the reference level changed when changing the device output slider. Also this would by itself explain the logic of Flat Volume I think. The device levels should only be used to be at 0dB for example when using 100% reference level, ie for "calibration" of the card. Also unfortunately some records are at low level so I'd add the option to not store a change in stream volume. When I'm listening to some silent record I don't want to get very loud output on a normal recording next time because I forget to decrease again to normal level. For example holding shift while dragging the stream volume slider in order to make a temporal change would be great. :) Regards, Sladi
