+## Title: All the emotes.
+
+MODULE ID: species_synthesizer
+
+### Description:
+
+Adds an action to Synthetic and Ethereal species that allows them to synthesize music.
+
+- Added to `modular_nova/modules/synths/code/species/synthetic.dm`:
+  - Edited `/datum/species/synthetic/on_species_gain()` to add the action to the mob.
+  - Added to `/datum/species/ethereal/create_pref_unique_perks()` to add the "Musical Discharger" species perk.
+
+### Master File Additions
+
+- Added to `modular_nova/master_files/code/modules/mob/living/carbon/human/species_type/ethereal.dm`:
+  - Overrode `/datum/species/ethereal/on_species_gain()` to add the action to the mob.
+  - Added to `/datum/species/synthetic/create_pref_unique_perks()` to add the "Tone Synthesizer" species perk.
+
