Extra audio outputs of one plugin may be ignored - by the next plugin if not used. - -Currently plugins with no audio outputs are not really useful in MusE, - chiefly because plugin control outputs are not used or displayed. -Nor are specialized plugins with many inputs and/or outputs. - -Nor are so-called 'realtime' control plugins which use audio inputs - and outputs for control signals. -<<< - Loud noise alert!

It will process the left input only, - separating it into stereo with the Comb Splitter, passing the - split stereo signal into the Stereo Echo, finally producing - stereo output available at the Audio Input track's output routes. - - -One improvement would be not creating unused redundant plugin copies - between plugins in stereo tracks. -For example, for a plugin having one audio input and one audio output, - feeding a plugin having one audio input and two audio outputs, - the extra copy of the first plugin is redundant and not required, - but currently it is created anyway. - -
