Check out the Manual pages 170 through 174.

The way to ad sweep effects, usually means having a moving filter. If you can recreate the sweep by manually raising the FilterQ (second knob from the top left) and then sweeping the filter (top left knob), then all you need to do is automate that movement. That is what the Filter Envelope is for. The panel has the Filter Attack and Decay knobs (the Sustain and Release is in the patch and you have to use the screen to tweak those) with which you use to set the speed of an upward sweep (attack) or downward sweep (decay), but they won't do anything unless you go into the patch and adust the Filter Envelope amount to something higher. This makes the Filter Attack and Filter Decay take control of the Filter Cutoff (as if it were tweaking the knob instead of you). The way it works is that if you put Filter Envelope Amount to full and put the Filter Cutoff to Zero, then the Envelope sweeps the filter from zero to full based on the settings of the Attack Decay Sustain and Release of the Envelope. You may not want to start the filter at zero (no sound) so set the cutoff to the place you want the sound to sound like at the beggining (or end) of the sweep. Then adjust the Envelope amount to taste as well, setting full makes the filter go to full and it may stay there for a while if the attack is still taking its time trying to push it up further than it can go (this happens if env amount is full but filter cutoff is more than zero). If you want a sweep that only goes so far, then bring the value of Envelope Amount down. Once you have the timing and scope of the envelope the way you want it, then tweak the filter cutoff and filter q knobs to get the sound of the sweep you want. Use the Filter Decay and Attack to tweak the timing more as well. Then save your new sound into a user preset.

  Subject: [xl7] Add sweep to preset


  I'm a beginner at best when it comes to editing presets.
  Is there an easy way to add a sweep effect to a preset or an 
  instrument? The one I was interested is in xl-7 bank 3 #57 
  bpm:bubbler.
