DMDX 5

    Last Updated: 09/06/17 j.c.f.

    This is the help for DMDX version 5, Dmastr for Win32 (Windows XP, Vista, 7, 8, 8.1 and 10) with DirectX 9.0 or later.  Version 1 worked on 486 class machines, Version 2 of DMDX dropped support for 486 class machines allowing much more accurate timing and generally cleaned up a lot of stuff like multi-monitor support.   Version 3 cut support for Windows 95, radically restructured the Audio Input and introduced the DMDX installer and .CHM help files.  Version 4 added Unicode support and addressed the long standing trouble DMDX had with other applications stealing it's focus.  In addition version 4 also introduced Auto Mode that allows DMDX to operate without the use of TimeDX.  Version 5 adds a Direct3D rendering path that is required for Windows 8 and later operating systems as DirectDraw (the original rendering API) is now emulated.  Version 5 also dispenses with operating systems earlier than Windows XP.
