Posted: Thu Feb 18 2010 00:26 the key for "off" on my keyboard is missing!
After pressing the Z key on my keyboard which looks to corrospond to "OFF" as shown on the quick start guide (http://www.madtracker.org/documents/quickstart.xml?page=4), it comes up as the note C instead.
Then I realised there's one less key on the second last row of keys on my keyboard than on the displayed one on the page (12 instead of 13)
