Creating Transpose buttons for Keyboard

Okay, so i'm having trouble coming up with how to get this to work. I have 12 custom buttons functioning as a keyboard. I want to create two other custom buttons that will incrementally increase or decrease the range of the keyboard by octave. I cant figure out how to get the the script to recognize the midi note numbers in the midi mapping page. I thought it would be similar to identifying an attribute in an object, but i just cant figure it out.
Any help would be awesome!

There are many midi keyboards in the user library with transpose buttons to check out the logic. It boils down to creating a custom variable, let's name it "pitch_offset", then create a custom midi out message and use scripts in the transpose buttons to increment-decrement the "pitch_offset" variable which will then be added to the "base" pitch of each custom midi message.

Thanks for the reply! I know what your saying and I had a look at some of the keyboards in the library, I am absolutely noob at programming so I get confused when theres so much going on. Looking at these templates made me realize how much potential lemur has if only I understood programming... so one more question. Is there any recommendations on some beginner scripting concepts for lemur, I have already read the manual, and it goes through some very basic stuff, but I just don't know where to look to get the information. (obviously here but don't want to bombard the forum with beginner questions) Again thanks for the reply.

Hear ya! Well, indeed, due to the vast posibilities I cant think of any "beginner-friendly" method other than downloading user templates with ideas that might be of use to you and analyze the scripts and try to comprehend whats going on.
