DirectX Media Objects is superseded and is not developed anymore.

Is this something that MPT should support further on. There was never made many plugins to it and I dont know of anybody using the plugins. Maybe it would be easier for the developers just to remove the support for DMO if it makes it easier to continue developing MPT.

DMO plugins are just "wrapped" into the existing VST plugin code, so the lines of code dedicated to DMO handling are about 400 in total for the audio processing - that's not much at all, so it wouldn't make things easier at all. Plus, they are the only plugin type supported by XMPlay / BASS, so they allow fancy sounding modules using those programs / libraries.

There were some big supporters of the DMO architecture (f.e. the Waves bundle was available as DMO as well as VST for a long time), but I think the biggest use of those plugins comes indeed from the fact that they are available on virtually every Windows installation.

Yeah, although it is good to know, that the plugins are different depending on the operating system. If you use Windows XP, it will sound different than if you use Windows Vista.

As Jojo says, the only real reason to keep support is that they're also workable in XMPlay.

I assume you are talking about the effect plugins that come with DirectX 8 and higher (i.e. the ones that OpenMPT knows by default), and in that case the only difference is in the WavesReverb plugin, which seems to have been modified slightly (on a level that is not noticeable) - if you don't believe me, create a module with DX plugins and render it under the exactly same conditions on WinXP and Vista/7 - it will sound identical.

I gave more than just that reason, and for it's clerarly not the only reason, but all of them are a good reason.

Uh... yeah X)
