## Ambisonic and cartopol simple math question

Mar 10 2009 | 3:42 pm
Hello,
I've build a simple visual aid with an lcd to set the position of my channels with ambiencode~ from ICST, but i can't find out how to match their coordinate system where full left, f.e, is -90 and full right is 90 degrees (as shown in the picture in the patch).
Could someone help me a little bit with simple math trick ?
Here's the patch. Double-click in the [draw_tool] subpatch to find the cartopol thing.

Put a swap object between your pack and cartopol objects. See below.

The 'ambimonitor' that works in Max4 is awesome. Is there a reason you have to do it in Max5?

@mzed : there's a swap.
@dodgeroo : ambimonitor is an ui object that has to be re-wrote with the new api.
best

@f.e
ambimonitor is out in beta, but not ambiencode...
I felt free to further modify your draw_tool to draw_tool_waj. So it works for me.
Note my speaker setup as
1 2 3 4
I also have my own color palette. I can send it to you by private mail.
