synth.audio-groups

Integer. [min=1, max=256]. By default, the synthesizer outputs a single stereo
signal. Using this option, the synthesizer can output multichannel audio. This
value should be the same as "synth.audio-channels" unless LADSPA is enabled,
then it will be the number of inputs to the LADSPA subsystem.

If you set this number to 16, each MIDI channel will be mapped to a separate
stereo output. If the number is less than 16 then audio_output# = MIDI_channel
module audio_groups.
