Pitch Shift needs fixed

Don’t know if this gets looks at but I use the pitch shift to tune my guitar up a step all the time in my Helix because I tune Eb and have some stand E tunes I play. The QC one works great going down step but the second you go up one and play anything that has a little palm muting it craps out all over itself and starts stuttering. So i basically can’t use it for any of those songs and still have to use a Helix. Just an FYI to anyone.
