The number of active channels in a MOD music.
|handle||The MOD music handle.
|active||The number of channels.
This attribute gives the number of channels (including virtual) that are currently active in the decoder, which may not match what is being heard during playback due to buffering. This time difference can be reduced via the BASS_ATTRIB_BUFFER attribute.
This attribute is read-only, so cannot be modified via BASS_ChannelSetAttribute.
