Hi, Are you talking about the wave reset in analog osc ? Because I put this "on" all time and the sound in this exemple has no OSC anyway it's resonant filter. Not sure what you mean by "rest after touch"
did some research and really look like it's a tempest thing as stated in this post forum.sequential.com/index.php?topic=78.0 "5) Assigning a sound to a voice can help but also produces a small click to the sound.It's very noticeable if you play fast bass or sustained sounds."
