Zitat:
Remarks
This attribute applies to playback of the channel, and does not affect the channel's sample data, so it has no real effect on decoding channels. It is still adjustable then though, so that it can be used by the BASSmix add-on and anything else that wants to use it.
It is not possible to set the pan position of a 3D channel.
Platform-specific
When using DirectSound output on Windows, this attribute has no effect when speaker assignment is used, except on Windows Vista and newer with the BASS_CONFIG_VISTA_SPEAKERS config option enabled. Balance control could be implemented via a DSP function instead.
Könnte es damit zu tun haben?
