The program can run multiple unique instances on a single machine. Each instance of the running program will use a separate database and be completely separate from other instances. The instances do not know of each other, cannot effect each other and cannot communicate with each other. Basically think of an instance as running on a separate machine.
To open multiple instances, use the menu:
FILE > NEW CUSTOM INSTANCE
For some info on custom db instances, check the thread https://rootjazz.com/forum /viewtopic.php?f=12&t=874
An instance can be opened by passing a single argument (the instance name) to the .exe. So if you want to open the instances up via an icon, create a shortcut of the .exe file from your c:program files folder. Then change the target to
"c:program filessoundcloud managersoundcloud manager.exe" instanceName
