Frequently Asked Questions

When you start Connection Open the application will default to one input channel. In some cases, the program won’t know what channel you want selected. For this, go into the setup audio hardware tab under Settings and make sure that you have the correct input and output devices selected. The octave lower sound, some even say it has a “demon-like” quality to the sound should go away. In general you will only want audio device selected as input. So put your microphone and/or instrument each on their own channel. The sounds should be gone now.

In general you will only have one device plugged in and working on Connection Open. In this case you will want to make your microphone “mono”. This will ensure top quality sound and is better for mixing. When using multiple devices, you will want to choose stereo and mono. This is to give you the impression of a full stereo effect for multiple mics or instruments.

In this case, it is probably a user error. The program will show all audio devices that have been connected to Connection Open. This means even if the audio device is not currently plugged into Connection Open it will still appear in the drop down menu. If you are seeing a device but cannot read the channel names on the audio set up, it is because that device is not plugged into or connected. If the audio device was plugged in after signing into Connection Open, make sure that the audio device is plugged in and then restart the program. The audio device have the channel names listed below in the audio set up.

Restart the program to detect new devices. Not for detecting installed drivers for the same device.

Connectivity issues: There are usually two different types of files sent on the Internet.


TCP – guaranteed delivery; first sends a little bit of data, ensures that the recipient receives the information and then sends the rest of the information. If the recipient does not receive the first amount of information, the system will not send the rest of the data until the first amount is received.


UDP – sends data to a port or address and continues to stream not knowing if the information actually made it to the recipient or not; If one bit of the information gets lost it may not be noticed and the information is continued to be sent


Because Connection Open uses UDP, we must be able to sent the information to the another machine. A lot of networks will not allow this to happen to security procedures. For example, if you are sitting at home, your computer is behind a router. The program needs to tell the router that it is going to receive UDP traffic on these two ports, send it directly to the computer.

When you receive this error message it is because the router needs to be adjusted. You need to make sure that your router allows traffic UPnP requests. Most home routers do enable this and all you have to do is go into your network setting and check to make sure that UPnp is enabled. On a Windows computer, this is pretty easy. With Apple Routers, this because a little more difficult. Most Apple airports routers need to be configured manually. OSX10.8 is common in the audio world and more current versions have not current issues with compatibility. In the 10. the air port setting utility has a bug. If you set up the UDP ports, but don’t set up the TCP ports (8095 8096) for UDP and TCP – set up the same ports for both. The air port setting utility will auto fill the IP Address incorrectly and with your air port router number. You will need to find the Internal IP address on your MAC.

1. Click the Apple icon on the upper left corner of the screen.


2. Scroll down and select System Preferences.


3. Click Network. (should be on the third row)


4. Select your connection. Typically you will be connected to the network via AirPort (wireless) or Ethernet (wired). The connection you are using will say Connected next to it. Your IP Address will be listed directly beneath your connection status, in smaller print.


When it comes to networking, one of the ramifications that this system uses is that multiple machines on the same network cannot run the program on the same network unless each machine has its own static IP address.


You will need to make sure that your computer has its own static IP address and the firewalls allow 8095 and 8096 to be open for UDP information to be received by the machine.

1. Open Network Settings.


2. Find the network connection that represents your connection to the Internet. Unless it is called Local Area Connection. Click on that and select Properties.


3. Select Internet protocol version 4(TCP/IPv4). Next select the Use the following Ip address.


4. Enter a valid ip address for the computer. Make it the first available IP on the network(not the router address, and not .0, or .255. As these are reserved addresses). If you are unsure of what address to use, find out the network address and make the local pc a host on that network.(if you are unsure do not attempt it until you have researched). Usually 192.168.1.1, or 192.168.10.1 will work.


5. After entering the IP address check the “subnet mask” has been filled in. This identifies which part of the address identifies the host(pc) and which part identifies the network.


6. Next fill in the Default Gateway, this is the address of the router or gateway device you are using to access the internet. This information can be found by checking your current(unchanged) config.


Go to Run.


Type cmd.


In the terminal window type ipconfig /all


7. This should tell you the default gateway, fill these numbers into the gateway field.


8. Next you have a choice regarding the DNS information, you can leave it to be obtained automatically (for simplicity).


For improved performance try setting it to a service such as “open DNS” which offers fast servers, to speed up the url to ip process, this might give faster web browsing(in theory). For this set “preferred” to 208.67.222.222 and set “alternative” to 208.67.220.220 .


9. Next select “OK”(optionally select “validate settings upon exit” if you think you may have made a mistake or are not confident).


10. Give the pc a second to apply the settings and check you are connected to the internet and can browse it OK. NOTE: that the last figure in the IP address you gave this pc, is the unique identifier. If you used 192.168.1.1(for Example!) then the last.1 is unique and cannot be reused whilst used on that pc. For the next Pc set it to 192.168.1.2(Example!) and so on. So each has a unique ID. Be careful not to clash them with each other or the router(or other device) or you will get errors.


11. You have now statically addressed your computer. Well done.
