Connecting to scsynth running on a Raspberry Pi wirelessly from scide on a laptop


I have successfully got SuperCollider to run on a Raspberry Pi 3 on boot with an scd file on the Raspberry Pi itself. I am currently trying to get SCIDE from my mac, on the same network, to control a server instance running on the pi. I haven’t found much documentation on this. Here is what I am doing now:

On the Raspberry Pi 3 (after starting Jack successfully) from a shell script:

/usr/local/bin/scsynth -u 57117 >synth_log &

On my mac, using the SuperCollider IDE:

    s = Server(\remoteServer2, NetAddr("", 57117 ));

I have already ssh’d from that laptop to the “” ip address successfully, so I know that the network is fine.
s.serverRunning returns false, which I assume means it didn’t connect.

Any ideas?


Hey Colin,

I think you want to take a look at Server.remote:*remote



Also make sure that port 57117 is open on the Rpi. The fact that you can ssh means that port 22 (default ssh port) is open, but probably SC port is not


Great, I am going to try this when I get home tonight and post the results. @Alberto_Gomez do you know the means of opening up local network ports on Raspbian? I am familiar with doing so on a web server via ufw, but I tried that command and found it was not installed on the Raspbian. So I just assumed all the ports would be open by default without ufw. I am fairly ignorant of how local networks work, though I’ve been able to ssh into the Raspbian. Sorry for asking a question out of the scope of SuperCollider, if there is a set of reading material for me to find to cure my ignorance, I will happily go searching for it.


I went looking for my own answer. It looks like I can see what ports are open with this command on Raspian:

sudo netstat -lptu

Will try this tonight and find out what ports are open and closed. It looks like there is no firewall on Raspbian by default. This command will hopefully clear up the question of whether or not I am having problems with ports.


Much thanks to everyone! I was able to get sound out of my Raspberry Pi with the following code on my SCIDE running on a seperate laptop on the same network:

o =;
o.maxLogins = 8;
s = Server.remote(\realtimepi, NetAddr("", 57117), o);
{ [, 0, 0.2),, 0, 0.2)] }.play(s);

Here is the output of Post window in SCIDE:

-> a ServerOptions
-> a ServerOptions
realtimepi : setting clientID to 0.
-> realtimepi
Requested notification messages from server 'realtimepi'
realtimepi - already registered with clientID 0.
realtimepi - handling login request though already registered - 
This seems to be a login after a loss of network contact - 
- reconnected with the same clientID as before, so probably all is well.

-> true
-> realtimepi
-> Synth('temp__1' : 1000)

In my shell script, I had to add jack_connect commands to hear the output. Because running sclang before made the jack connections for me, I forgot that step with scsynth. But as soon as I did that, I heard the sine waves over my Raspberry Pi!!!

Much much thanks!


I started a seperate question here related, but different from this one:

I am now trying to see if I can control the midi devices on the remote raspberry pi through the IDE on my mac. Feel free to comment there if anyone has insight.


@Colin_Brogan sorry didn’t see your message earlier but glad you found your way around trouble!
