I think I remember that is has something to do with the envelope, are they chords with really long notes or conversely really short notes? I might be wrong about this but I’ll look for where I read that.
also hyperstation is right it’s not the delay or chorus, it’s a guitar pedal (simple description) inside your digitone so it’s not using synth voices.
*I think people usually call it a clicking noise, if that sounds about right you could read this, there’s some explanations
the quick answer was try a shorter note length so I guess not the envelope, or maybe there was something about that in another discussion but I’d look at note length first, if it’s long notes. If not we’ll try and figure it out or whatever.
here’s something else with a video:
