I have added an insert post-fader on that Ardour track, then edited
that fader to specify output playback 3 and 4.  Now it is possible to
hear the LADSPA delay on that track when playing the hardware synth
but, only in record mode, shown in envy24 as monitor PCM 3 and 4.
A bit annoying since all practice and delay adjustments has to
be done while Ardour is actively recording. Is it possible at all to
monitor via hardware any effect that's assigned on a track w/o actively
recording ?  Card is M-Audio 1010LT. Using envy24 control.  Thanks
again for any hints.
