Ed , check the Tyros and make sure it is transmitting out the midi port..Maybe there is a physical or soft setting that has to be switch on the Tyros[in song mode]..
You did the correct setting on the TC [channel 5 for Tune 1000 sequences]..
As you already know I am not a Yamaha sequence playback fan... But midi parameters are the same on all models.. Let me know how you make out..
