This is the Max Patch level. just a sound for testing and i referenced the buffer to see what was going on.

this is the Rainbow patch (same as above) - Note the "Loadbang" as this will build the window to the buffer automatically when the plugin is Init.

This is the Gen~ folder. i highlighted the changes mentioned above.
i believe the no sound issue you are describing is that the effect is technically not on when exported. i did it this way to be able to add all that in HISE. Best Success hope this helps.
