It’s still there. If you load a patch containing it it will appear. You can edit the fundamental plugin.json so it’ll appear in the modules browser:
{
"slug": "VCA",
"name": "VCA-2",
"description": "2-channel voltage-controlled amplifier",
"tags": [
"VCA",
"Dual",
"Polyphonic"
],
"hidden": true
},
Just change “hidden”: true to “hidden”: false
Same with UNITY.
No idea why they chose to hide them.
