If Global Kill Dry is ON, then you can try setting the Mix parameter of Diatonic to 100. Leave its Kill Dry setting to Global. On the Reverb, set the Kill Dry parameter to OFF; set the Mix parameter to 50. The reverb’s Mix parameter will allow you to control the balance between the signal coming from the Diatonic pitch shifter and the effect from the reverb.
Something to note: if one of the harmonies on Diatonic is set to Unison, it will sound as if there’s dry signal because you’ve instructed the algorithm to duplicate the dry signal and output the same note (unison).
