Sound system compatibility - FMOD (http://fmod.org/) The following versions have been (more or less) tested: 3.20a, 3.30a, 3.32/3.33, 3.40, 3.50, 3.60-3.63, 3.70-3.75 Version 3.2x (and older) and 3.70 are not supported; When using fmod.dll older than 3.72, it may occur that audio tracks are skipped so the track is not yet finished.
Some older versions may work properly with the primary cd drive properly.
So different or missing API interfaces for older versions are handled by the layer, they are not fully tested.
FMOD does not support unicode filenames, the layer should handle this by handling file access (streams) and playing from memory (tracker, midi).
Using certain Systemtools, e.g. Handle or Process Explorer from SysInternals, may result in songs restarting while progress/time continues properly.
Installation:

| When using the setup version, choose FMOD as sound system
| When using the zip-version, you have to

| copy (overwrite!) Calaym.lay from in layers\fmod subdirectory to your Calaym directory
| download the current fmod.dll from http://ctuser.net/, or the full Windows package from http://fmod.org/ (fmod.dll is found in the 'api' directory). Extract fmod.dll to your Calaym directory.

| fmod.dll requires msvcrt.dll, which may be missing on Windows 95/NT4
