Hi Everyone,

I have a Mark IV and have a few questions that I can't seem to figure out.

1. Does anyone know where to purchase a new battery for the pda remote and any idea how 
much it costs?

2. I've been hearing you can connect the Mark IV to your computer and control it from your 
computer?  Is this true and can anyone help me to figure out how to do this?

3. I also can't find the information/instructions on connecting to live players.  I get emails 
periodically from Yamaha with news flashes of events I may want to listen to.

I have the Ver 3.0 software, wi fi connection.

Thank you!
  Brian
