Polychain for the modules is not implemented yet, but is very high on our feature request list. Stay tuned!
You mean for module > module polychain?
That post is obsolete now, polychain is now supported. Presumably module->module as well as keyboard->module or keyboard->keyboard.
AFAIK it’s limited to 2 units being polychained. So you can make a Take 10 but not a Take 15. (Or maybe you can?… I don’t have 3 units… just a Take 5 and a TEO-5… which I was able to polychain with some midi trickery).
