You came to the right place for a friendly discussion and help.
You should be using the app called "iWavit Tabula Rasa" or "Tabula Rasa HD" for the iPad.
How to get started with your Yamaha RX-Z9 (or any remote):The easy way (if it is available):
1. Go to "Edit" and select "Search Online":
If someone has already created this remote, it is a lot easier to just see what they have done before building your own. Chances are it will do all you need. In the Online Database, if you find a remote you like, you tap on the image of the remote and 5-10 seconds later you will have it in Tabula Rasa.
Unfortunately, this is not an option for you as I do not see any uploaded remotes.
2. Go to "Edit" and select "TV Remote Wizard":
This will present you with a very large database of remotes, all available locally on your iPhone/iPad. Select "Audio" and then "Yamaha".
There are 10 remotes to choose from. Which one is the right one for you? Press the "Test" button on each one. The one that turns on/off your Yamaha receiver is most likely the right one. Tap on it and the Wizard will build the remote control for you. Test out the rest of the buttons and see if it works. You can go back into edit and erase buttons or move them or choose different designs.
The Wizard uses a database of remotes that we have licensed.
This is what the Wizard created remote will look like. The Button-by-Button approach:
While building a complete remote in one shot is nice, in most cases many of us just use a handful of the buttons on a remote control, so it is better to build you own remote. Start by going into the "Edit" menu. Now select "Add button".
You can now edit a button by adding a function. Select the "Add Function" at the bottom and you will see a "Select Function Type" menu.
You can choose any of these, but I recommend trying out the IR learning. Once you get familiar with IR learning, it is by far the fastest way to add buttons.
See this link for an example:http://www.youtube.com/watch?v=bxgJ20KewVE
You can learn function into any button. You can even create macros, i.e. buttons that do multiple things when you tap on them.
Here is what the Button editor screen looks like:The Background Approach:
This final approach involves you either taking a picture of a remote and using is as a "background" image, or drawing a remote in any drawing program. In either event, once that image is on your iPad/iPhone you can go to Tabula Rasa>Edit>Edit Remote and select "Add Background".
You can now import any image into the background.
The final step is to overlay invisible buttons on top of key areas on your image. If you have an image of a remote you will want to put invisible buttons on top of the buttons. If you have taken a picture of your living room, you may want to overlay transparent "hot spots" on top of your TV or Sound System.
Once you have a button, you will edit it as before. Other approaches:
If all else fails, and you cannot learn an IR button for some reason, then try to go to the function editor and select "IR Library (Online)". This is a backup database of remote control codes. I do see several Yamaha remote control buttons there.
OR email us at firstname.lastname@example.org
and we will add it to our list of remotes to build.
So the next big request that we have heard is "I want more and prettier buttons!"
We are working on that
In the Tabula Rasa 3.1 we added over 160 new buttons. In our next version coming in about 10 days, we will be adding another 250 beautiful button designs. This version will also include truly invisible buttons to overlay on background images.
Finally, regarding better documentation, yes we are working on that and trying to keep up with all the changes we are making to the app.
We are creating video documentation and an advanced user manual as well as more in-app documentation. Of course ideally it would all be self explanatory.
