JP1 Remotes

Can anyone help me with the following problem:

I am trying to make an update with KM for Sony STR-DE675 receiver. I first learn the buttons, and download the protocol/device/OBC info to IR.

The problem is, that my receiver uses the combinations mentioned below (so far, i'v learned 50% of the buttons):

protocol / device
Sony12 / 1, 16 and 13
Sony15 / 144

How do i make a update to this ? Is there a way to put in more that 2 device numbers for the Sony12/15 protocol on KM ?

You need to use the Sony Combo protocol if you want to get all the functions into one upgrade.

Once you figure out how to use a combo Protocol you can look here http://www.hifi-remote.com/sony/ for additional commands that might work that aren't on the original remote (like discrete commands). If the listings match up with what you're learning you might be able to build an upgrade without having to learn all the buttons. The listings use OBC and it might be a little confusing at first but once you verify the protocol and device numbers being used on your stereo , extra commands are at your fingertips.
