mono instrumenttrack

hi,i want everything below 175 hz in mono
when I import a kick on audio track I create a mono track
but how do make sure bass is in mono? as im using instrument or midi tracks?

  1. Put a plug with mono switch on the track
  2. Route to a mono group
  3. Use the Safe Bass control on the excellent and free A!StereoControl VST plugin (there are other options of plugs for this)to mono only the low end at the frequency you select so you only need apply it over the whole mix or to a stereo group of instruments that you want to treat.

thanks for the reply
if the synth dosent have mono switch,does that matter?
