What I have noticed is that every time you reboot the software you have to "retrieve" the inputs. Othewise it always shows the default settings.
I have also noticed that you have to retrieve the settings on few places. E.g. speakers (seperately from the inputs), tones (seperately as well). When you do the changes it seems that you are doing automatic changes on the Mach but once you log off, you start the process from the beginning...
I have also noticed that if you have different PEG and tone settings for each input, you have to switch to the input to be able to see the different settings. If you change them only on the default page, you see the settings on the input which the Mach is playing, not what you changed on the default page..
Hope this helps.
