|0001279||OpenMPT||Plugins / VST||public||2019-11-05 23:24||2019-11-06 07:36|
|Product Version||OpenMPT 1.28.08.00 / libopenmpt 0.4.9 (upgrade first)|
|Summary||0001279: opl samples do not send audio to plugins not labeled "master"|
the new opl instruments don't seem to send audio through vst plugins unless the latter are set to "master". if they're only assigned in the instrument tab, or even on the channel, they don't work.
|Steps To Reproduce|
i've searched the bugtracker and the forums and couldn't find anything on this behaviour.
|Tags||No tags attached.|
|Has the bug occurred in previous versions?||untested|
|Tested code revision (in case you know it)|
The OPL chip has a single combined stereo output and this is also how OPL emulators work in genral. As such, there is no way to "extract" the output of a single OPL voice from the stereo mix and send it to a specific plugin. If instrument 1 was assigned to plugin 1 and instrument 2 to plugin 2, there would be no way to know how to "split" the signal because it's not possible.
In the future we might be using a separate OPL chip instance for each instrument in MPTM format which would enable us to work around this limitation, but until then there is nothing that can be done about the current behaviour - it's very much by design.
