How to get unison to work with Scriptnode Synth?

[ally]

I have a scriptnode synth in a synth group. When I try to use the synth group's Unison, it adds voices but doesn't detune. The case is the same whether I keep the network uncompiled or add it as a hardcoded poly FX on a silent synth. Pitch mods aren't working either, so I'm wondering if maybe I'm missing something in the network?

Here's my module tree setup with both uncompiled and compiled versions of the network:

And here's my network setup in scriptnode:

Any ideas as to what I'm doing wrong would be appreciated!
