LNX_Studio is designed for collaborations in real-time over the Internet or a Local Area Network.
As a User you have a simple profile which you can edit. When you connect, your profile appears in a room along with anyone else in that same room.
Rooms are places where you can meet people and start a collaboration together. When you first start using LNX_Studio you will be connected to the room home. This is a special public room designated for meeting people. Once here, you can invite or be invited to a public or private room to make music in. Or if you wish you can create your own private rooms and arrange for people to meet you there instead.
Once in a collaboration you are making a Group Song together. All the instruments created in this song are available for everyone to hear, edit, copy and delete. There is no ownership or license agreement prior to starting a collaboration, that is for you to sort out amongst yourselves.
The best way to start an on-line collaboration is using a VPN like Hamachi. https://www.vpn.net. A VPN enables users to send and receive data across shared or public networks as if their computing devices were directly connected on a local network .
The Hamachi service is free for 5 computers and once you are signed up you can either create a network or join an existing one. Above we have 2 people connected on the lnx2.0 network. Andy has the IP address of 220.127.116.11 and Neil has 18.104.22.168. These IP address can be used in a LAN connection below.
Linux: Haguichi provides a graphical frontend for Hamachi. https://www.haguichi.net
All LNX_Studio requires for a LAN connection is the IP addresses of the computers being used. There is a search facility which looks for them for you, but if that fails you can manually type in addresses you wish to search.
OscGroups is a another way to start internet collaborations. This method is less reliable than using a VPN / LAN and will be deprecated in future versions.
A Server is needed to send all the real-time messages from one machine to another. You can create your own Server (see network preferences) or you can connect to one already running on-line. Currently a server is been maintained at realizedsound.moo.com
LNX_Studio uses a client program to connect to these servers. If you have security software then allow LNX_Client to communicate on port (22242). If you have a firewall installed on your machine you may need to ensure that the LNX_Client is registered. If you update the program you may need to re-register it.
To start, open the Network Window. This is in the File Menu or press the [Net] button in the studio window.
The Address Bar runs along the top, the Room sits below that. A list of users in the room is on the left and a chat room dialog to the right. Profiles can be seen below the dialog and people can be invited in the bottom section of the window.
When connecting via LAN you need to specify which IP addresses are being used. The address bar has two purposes: to set which IP address you are using and to search for other peoples IP address
When connecting via the Internet each room is comprised of 3 things: a room name, a server address and a room password. You can move to or create a new room by typing its name, address and password here and then pressing Go. If the room doesn't already exist then the server will create one for you. Then only people with the same room name, address and password can enter that room. These rooms are managed in the Network Menu.
The address bar has several purposes: to set which IP address to use or to search for other people by IP address
All rooms named 'home' are designated as public rooms (a place to meet and invite people into separate private rooms). If you want to make music in a public room there are 3 rooms called studio1, studio2 and studio3 enabling you to do this. All public rooms use the password 'password'. Whilst in these rooms you have the option of hiding your email and Skype name.
All other rooms are called private rooms because you would either have to know of their existence or be invited to one by another person. You are able to make music in these rooms without been disturbed by users you haven't invited. Once in a private room your email and Skype will be available to the people in that room to view.
On the left hand side you can see a list of users in the current room. If their name starts with an asterisk * it means they are in collaboration. You can click on any of these and their profiles will be displayed in the profile tab on the bottom right.
On the top right is a chat room style dialog box with a text field to add your own text in. Other useful information will be displayed here.
There are two profile tabs. One called < Profile used to display other peoples profiles and one called My Profile where you can edit your own profile.
The fields in the profile are:
None of your personal information is kept by the server, it is stored locally on your machine. It can be found in the folder /users/user/library/preferences/lnx_studio/userprofile. You can only have one profile on your machine at a time and this will be used whenever you load LNX_Studio. By default your email and Skype name will not be shown in public rooms. This can be changed in the network preferences. I recommend that you don't put any information in your profile you don't want others to know about.
To Host a collaboration you need to make a list of users and then invite them to join you.
Once you have invited people to a collaboration you will need to wait for them to agree to it. You can not invite people who are already in a collaboration.
The 1st invite is from the Host's machine, waiting for responses to his request. The 2nd invite is received on the User's machine and awaits their confirmation. Both show a list of who has said yes and no.
You can manage the rooms and locations you visit from within this menu.
LNX_Studio uses the programs OscGroupClient and OscGroupServer by Ross Benciania. You can read more about them here.
In the context of this program I have renamed them both as LNX_Client and LNX_Server. I am not taking any credit for these great programs. I have just renamed them for the sake of continuity. When a user looks at the Activity Monitor they will be able to see LNX_Studio, LNX_Client and LNX_Server running side by side.
If you want LNX_Studio to connect to your Home room when it opens then select On Open [Connect to server]. You can choose to show or hide your email and Skype name in public rooms. Normally the client connects to the server on port 22242 but this can be changed here if conflicts with other applications occur. For this you would need to create your own server and the port it listens to.
If you want to start a server when you open then select On Open [Start a Server] If you then want it to quit when the studio closes then select On Close [Quit server + terminal].
You can set the following parameters prior to launching a server. Any changes made whilst its running will take affect after it's re-launched.
The server will be launched in a terminal window and you can monitor its traffic there. To start and stop it manually use the Start & Stop button. The icon on the right will show you the current server status.
In order for the server to work you need a static IP address. If you are behind a router you can find this by using web sites such as:
This will then be the server address that others need to connect to. If you are using a router you will need to do port forwarding from the router to your machine on Port (22242). You can find out how to do this in your router's instruction manual. Note: If you have security software then allow LNX_Server to communicate on Port (22242) or whichever port you are using.
