The multichannel audio goto command was one of the bugs in d3, so I tried it immediately after downloading d16, and it failed to work in the following order:

0:00 - Load track
0:00 - Goto x:xx
0:00 - Volume xx
wait - Play

If I have a wait time of 0:00 between Load and Goto it doesn't work but with 00:15 it then works. It also works if putted after the play command with a wait time of 0:00. Is it necessary to have this little delay between the Load and Goto commands?
