What’s up with the djfx looper?

Dunno what’s up but it seems like the post was not approved or smth... here I go again:

Ok so I had this issue since I started with the sp but I never figured out how to solve it:

If:

1. the djfx looper is turned on
2. the resonance knob is turned all the way to +1
3. the djfx looper itself is set to off (via the right poti knob)

The sound should NOT be affected at all right?

Why is it that I sometimes get some kind of delay of the incoming signal?

Emphasis lays on sometimes... sometimes there is a delay, sometimes there isn’t...

If the looper is turned to off the sound is NOT affected by the “len” button (cutoff), right?

Appreciate any kind of help!

Thx in advance
