How can I create an internal granular synth in an ensemble?

I'm working on a project at the moment which is a fairly simple subtractive/FM synth, I want to implement a basic granular synth macro inside the ensemble, that would allow me to record the sound coming out of the "main" synth macro and use that for the granular macro instead of a pre recorded sample that I would have to import into reaktor. I understand that there are much easier ways of going about this, but im doing this for a school project and I need to be able to implement it inside of the instrument itself. I am so far able to record the output with a recorder module, but I cant work out how to use the recorder macro as the sound source instead of pre recorded samples.

I'm aware that Chris List's "live grain cloud" macro does exactly this, but I cant seem to get it to work. Ive attached some photos of the routing for context.

Ff anyone has any suggestions for a solution/workaround to this that would be amazing.

thanks.
