The Orchestra Manager is where the user organizes and edits the orchestra for the project as well as their user Instrument Library.

In the User Instrument Library (the tree pictured on the left), you can create instruments as well as categorize them into groups. Most actions in this editor are accessible by right clicking with the mouse to access popup menus. (keyboard shortcuts of ctrl-x, ctrl-c, and ctrl-v work for cutting, copying, and pasting nodes of the tree). To edit the name of Instruments or Groups, double click the name in the tree or hilight the node and press F2. This library of instruments is available across projects and is useful for building up and organizing a personal instrument library. To copy instruments into the library from the project's Orchestra, you can drag and drop the instrument on the library tree to make a copy of the instrument. To copy an instrument from the Library to the project's orchestra, select an instrument in the library and use the ">" arrow button.

The Orchestra panel (located in the top right of the picture) is where you will organized your instruments to be used for your project. The three buttons to the left of the Arrangment table will add a selected instrument("+"), add a selected instrument from the user's Instrument Library to the project's orchestra (">"), or remove a selected instrument from the Orchestra("-"). Once instruments are in the Orchestra, you can edit what their instrument ID's will be, be it a number in classical Csound style or a string for using named-instruments. (i.e. 3 for "instr 3", violin for "instr violin").

In the bottom right is where the instrument editor for the selected instrument is shown.

Depending on the blue instrument-type, different editors will appear here when selected in either the Orchestra table or Instrument Library tree.

For projects before 0.94.0, imported projects will have their instruments largely setup in the same way as they were before.

For projects that were in the 0.94.0 beta series, per-project Instrument Libraries will be removed. An option to import the instrument library will be presented to the user and if the user agrees, a folder entitled "Imported from Project" will be added to the root of the user's InstrumentLibrary. On the whole, it is recommended to import the library, review the instruments, and simply remove what is not necessary. Deleting the imported library is as simple as deleting the folder for the imported group. Instruments in these project's Arrangements will be modified to hold copies of the instruments from the library as opposed to being references to instrument in the library. (Previously, if two instruments in the Arrangement pointed to the same instrument in the per-project InstrumentLibrary, changes to the instrument in the library would affect all instruments in the Arrangment that pointed to it. Now, only copies are made and no references are used.)
