Trying to go about making a guitar fretboard using the pattern feature and an expression - however I'm not sure how the expression would go. Any advice would be great. Ultimately would like to do something like this: http://www.mykaguitars.com/instruments/121/121-010.jpg
If you have a simple increment you can just key in the "growth rate". This means that the distance between every pattern instance will grow by 20 (mm).
Spoken in math it will be something like d(n+1) = d(n) + x; x is my 20 and d(n0) is my first distance set up in the pattern dialog.
Having entered your desired count and a starting pitch value, select the Pattern Increment icon:
Highlight the Pattern direction parameter and select "Add new set":
Enter in the desired incremental value and choose OK to return to the Pattern Feature dialog:
It's hidden for your convenience
Click on the Dialog Options icon at the bottom of the dialog and choose "Pattern Feature (More)":
Ok I see it now. Cool - a couple more questions: is there a way to have it decrement instead of increment? Also, how could you have this affect other properties - like scaling or rotation? thanks
