sorry for  late answer.
Yes iem_ambi was programmed before ACN becam standard  ;-).

I did a conversion abstraction SID, ACN, ... in my ambisonics multichannel 
library:

- https://git.iem.at/pd/acre-amb

 which uses a encoder which changies the order:

- https://git.iem.at/pd/acre-amb/blob/master/spat/ch%7E.pd

Note: Experimental library with dynamic patching, you have first install acre 
library and install amb in the acre folder, then open examples.
