Hi I was wondering if I could obtain the documentation on the data protocol for the GB-580 when downloading tracks over the usb/virtual serial port. I'm writing a python script that can interface with the device, download tracks and store them in any number of formats. This will hopefully become more portable between different OS'es (i.e. linux, mac, or windows), etc. I have a pretty good idea of how this works and can work backwards somewhat, but having the specs will save me some time for one, but more importantly it will allow me be more thorough in supporting all the features.
