VST Connect & VST Connect SE - Solution Thread

I would love to see this work…I cannot get it to work.

Does anyone have this working reliably at this point? If so did you have to set up your router any way special?

I can log in and get a key, but the 2 machines fail to connect to each other.

You have to port forward udp ports 51111 to 51113 on both sides. But I can not get it to work even after that.
I can see the traffic coming to the computers on each side but nothing happens.

I was able to set this up with a buddy. We could see each other from the webcams (The video is flaky to say the least)and hear each other from the To Performer and Performer monitor but I could not record his audio using the built in template. No audio is passed through the “Performer Rec” channel when sourced to “TB/Performer”. I have followed the guide and the video to the T but with no success.

Then the implementation on steinbergs side is insufficient , as the combination of ip/port should be unique for each machine.
Networking for beginners…

So true, and the server should respond to the client source port not the fixed 51111 or 51113.

And NAT should be no problem. …

Did you have to forward the ports to get this much to work?

I had to open ports 51111 to 51113 on my router so that my buddy could connect. Problem still that I cannot record him.

I port forwarded to my computers ip address and I was able to connect to a remote machine, but it would time out in about 5-10 seconds.

Duracell: your findings are correct, but there is no particular order in which the nodes connect to each other. In fact, they both attempt to connect in parallel until one gets a reply, and they reply to the translated port too (NAT traversal).
Thus I’m surprised that your connection doesn’t work, if Wireshark shows incoming packets, a reply should be posted (you should see that in the Wireshark logs…no?). Can you provide more details?
R: if you can monitor your partner you can certainly record him. That’s nothing to do with VST Connect, normal Cubase recording business…you did set the Performer Record track to record enable…?
Video will also be enhanced in the next update.

There is indeed a timeout of approx. 8 seconds when there is no activity Possibly…if neither audio nor video is transmitted from the other side, the timeout might be hit - we’ll check. OTOH a connection without both video and audio doesn’t make much sense :slight_smile:
Did you try this more than once?

Good to hear about how the connection is established, then what I saw on the wireshark log make some sense. My computer was still in the establishment phase. I will keep you updated on my findings.


I did some more tests. Here are the wireshark log files (open with wireshark).

Both computers are macs running OSX 10.8.2

studio running cubase 7.0.0 is behind a router/firewall with port forwarding ip
performer running VST connect SE performer has a public IP-address.



We did a crude test…so perhaps what you say is the problem. I will try to test with someone else shortly.

I have the same problem. We connect and then disconnect with “Connection Timout, Disconnected” message. We have forwarded all port 51111-51113 (at both ends for troubleshooting), tested the forwarding with PFPortChecker from portforward.com. Tried putting both the computers on the DMZ… same problem. Leave this off, it won’t make a difference if the ports are forwarded properly. Should I enable ping on WAN? I’m about to.

I went to speedtest.net and tested my internet speed and his. Both have 3.5mb upload and 26mb download - and 16ms ping on his and 15ms on mine. Way more than the requirements of 256kb upload and a great ping.

Both running 64bit Windows 7 - Performer has nothing but the client performer software and a Behringer usb audio input which when my track was set to 96khz and 32bit floating, I got a message from VST Connect that I had to change to 48Khz and 16 bit to match the settings on the performer. It made a proper handshake there.

I can see the Performer audio settings - for the 5-10 seconds it stays connected. It is really connected.
He has never been playing while I’ve been connected, not sure if we would hear anything.

I tried to set my remote delay compensation to various levels up to 20 seconds. Still drops within 10 seconds.

I’ve used the preset template and made 2 of my own - I understand how it works. Performer Group track routing is TB Performer in and To Performer Output. The VST Connect and SE plugins come alive during the connection. They are in the Insert locations on the input channel for VST Connect and the performer group channel for VST Connect SE.

Is there something we are doing wrong? Do I need to enable ping on the WAN? Is there an update that solves this?

If you get connected, everything related to your internet connection, ports etc is set up and working, no need to search there. Also this has nothing to do with how Cubase is set up.
We looked it up and the only explanation is that the Performer has no audio and no video connected. The performer can set this up himself using the VST Connect SE Performer application:

  • start the VST Connect SE Performer application
  • click the “Conf” button on the right hand side
  • make sure an active “audio device” is seleced. If none is present, download and install ASIO4All (assuming this is Windows; on the Mac, there should be a system audio device) available at www.asio4all.com
  • if possible install a webcam and select it in the “video device” setting.

Does it work now?

SUCCESS! This thing works amazing!

Had to forward ports 51111-51113 to my computers ip address…and do the same on the other end.

Now that we were sending video and audio no time outs or drop outs…it worked flawlessly.


I am using the default VST Connect SE Template and testing with a friend. The remote client’s audio is heard on the Performer Monitor channel in my studio but as soon as I play or record the audio is muted and no audio is routed to the Performer Record channel so I cannot record the remote user.

We can communicate fine both ways over the “performer monitor” channel. The recording is supposed to take place on the “performer record” channel but I see no meter activity on this channel and nothing is recorded. Both the Inst and Conf buttons are activated so when the remote user has a microphone and a direct guitar I can hear both independently over the “performer monitor” stereo channel.

Has anyone been able to record the remote user using VST Connect?

It could be that you have the “Instr.” channel activated on the Performer. In this case, the Performer’s “Mic” channel functions as a talkback only and is muted during playback/record so to record the instrument only.
