HELIX PITCH TUNE DOWN PROBLEMS

Recommended Posts

Hello, I have a HELIX LT. I use the PITCH WHAM or SUMPLE PITHCto change the tunning down or up (depends on which guitar I use) But it sounds bad. While the pitch change is good it does have a wavering sound like a tremolo. with distortion playing loudly it is little noticeable but in clean tones it is very annoying. 

 

Im using 2.83.0 version and my setting is:

Interval -2 

position 100

cents 0

delay 0

shift level 100

mix 100

The Helix range of devices are not polyphonic.  That means that it cannot handle more than one note at a time.  Also, the further you change the pitch the more of a difference you will hear.  Your settings look OK for a full step drop.  If you want a more accurate reading you will want to get a Digitech Drop or other polyphonic pitch shifter.

I have a video that compares the Helix to the Drop pedal.

Helix doesn't currently support polyphonic pitch shifting, which means that these effects work ok for single notes but will exhibit the sort of artifacts you describe if you use chords.

Polyphonic pitch shifting is apparently being looked at for a future update, but it is some way off and certainly won't be in the next release.

Really looking forward to an update on the Helix Pitch Wham. I bought a Digitech Drop to compensate in the meantime, but it doesn't match up to the Kemper Transpose effect. I guess the Digitech is quite old now. I think there is room for Line 6 to do something great with this.

As already mentioned, there is no polyphonic pitch shifting, but volume is also very likely part of your problem. At low volumes, you are also hearing the guitar acoustically... and before you say "couldn't be", I promise you, it happens...every time you play at low enough volumes.The acoustic sound of the instrument is easily ignored when it's the same pitch as the sound coming from your speakers, but when those pitches are no longer the same (and especially at close intervals) you will hear dissonance. This is a well known phenomenon to anyone familiar with either the Digitech drop pedal or Variax users. You gotta turn up loud enough so that you're not hearing the guitar itself anymore...it's not an option.
