[Line6linux-devel] General method of controlling a POD XT USB device?

[Boyd T. <bti...@gm...>]

Could someone explain the general method of controlling a POD XT USB device?

I'm trying to wrap my hands around how this all works.  From what I
can tell, with older POD devices, you had to plug in a MIDI cable to
control the device (i.e., change amp models, effect settings, etc.).

With the newer PODs it looks like the controlling can done via USB.
My question is:

1. Do you control the POD using MIDI packets/commands still over the
USB interface

 -- or --

2. Do you use some other direct USB command to do the controlling?

I was fiddling around with the MIDI API in OS X just to get an
understanding of how this stuff works, but my POD X3 Live never seemed
to respond to any of the MIDI packets I sent it.  So now it's got me
wondering whether I should be using some other USB-direct command.  I
tried reading through the line6linux driver code, but I'm sure I'm
missing something because I haven't read through any driver
documentation for Linux yet.  It's on my todo list next.  :)

Thanks for any help you might offer,

Boyd
