Just confirmed by test, MMTTY is backwards compared to all other Software. Others idle on the high tone MMTTY idles on the low, unless the REV is pressed.

From Wiki
the upper tone used for idle condition (MARK).

Another site says
You also have to switch the correct phase position (whether the lower or higher frequency carrier in frequency modulation corresponds to "Mark" or "space").

Mind you a Ham education site on the subject says.
Remember that bfo’s help filter out the carrier waves to allow for the original signals to come through
