Hi Itai
some of the Ultra-Shifter presets are meant to sound "weird". For instance 5610 Robot Voice does … a voice robot.
Other presets need to be used with some attention:
-if you need to alter pitch in specific scales, then use any of the 3 Ultra Diatonic presets. If your needs are relative to the chromatic scale, you could use Ultra Cents or Ultra Interval presets.
-Ultra Shifter is meant to be used *only* with monophonic (vs. polyphonic) vocals tracks. It may sound ok with other sources but it's just beyond its scope.
Your levels seems ok. No need to set your audio interface on High output gain.
For the LEDs after entering/leaving the Patch Editor, we'll have to look into it.
al the best
