for Windows platform, I suggest Audio Mulch and to employ 2nd-order
Ambisonics methodology for setting the virtual position of each sound
If the position of each of them is fixed, You preferably will first encode
each sound in a proper 9-channels FMH file (employing the B-Pan freeware VST
plugins by Dave Malham), and store all these files on the HD.
For playing them, use the 2nd-order B-player free VST plugin from Gerzonic,
feeding an Ambisonics decoder (either the Malham or the Gerzonic's one).
You can have many instances of the B-player plugin, and activate each of
them with a Midi command - so, for example, a Midi keyboard can have one
sound attached to each key...
The only limit with the above apporach is that Ambisonics require that the 8
loudspeakers form a "regular" array, such as a cube or an octahedron...
If You want, I can create the AudioMulch "patch" for You...
P.S.: happy new year!
