I have the syrincontrol mod installed, but it only works with the online player, not with my basis syrinscape. I contacted the developer and got the following message:
“That is a problem on the Syrinscape API side, not something on my module. I would recommend writing to the Syrinscape team on their forum. They tend to respond in a couple of hours.”
To be clear I am have bought and installed syrinscape, I have foundry working and the mod downloaded, but as I said, the sounds linked in foundry can only play trough the online player.
