That’s already possible. Go to your bot webinterface, login with the admin password. Then settings -> discord server settings -> default text channel. Then the bot only outputs into this set text channel on discord.

Bot text channel output
The ability for the bot to output the text and playlist output in the text channel of the respective voice channel (Discord).
Furthermore, it would be nice to be able to configure it so that only the playlist output (current song) is posted without any other bot messages (error messages, commands, etc.).


Or do you mean the text „channel“ which is combined with a Voice Channel?

It’s untested but you can try to set the Voice Channel id (you can find the one for the start voice channel list), copy the channel id from the voice channel and save this one into the default text channel setting. But I did not test this. Maybe the discord api then sends it into the voice text channel.
