Boss VE-500 ... Pitch correction disturbed by acoustic guitar

[Boisdelac]

I recently purchased a Boss VE 500. To control the harmonies I use either my electric guitar or my acoustic guitar equipped with a pickup. When I have pitch correction turned on in the VE 500 and I play my acoustic guitar, unusually tones (unaccurate pitch, phasing, flanging) occur in my singing voice. I suspect that the acoustic guitar also interferes with my microphone (Beyer Dynamic Soundstar Mk2) and thereby distorts my singing voice or the pitch correction. How can I prevent this?

Pitch Correct and Harmonies are two separate functions in the VE-500.
For pitch correct, try SOFT type, and Chromatic for the scale.
If the scale is set to KEY, then you have to be playing in that predefined Key.

The acoustic might be a bit rich in harmonics for the pitch tracking to follow, maybe dial the treble end down a bit.

I know that pitch correction and harmonies are two different things.

My problem is, that the sound coming from my acoustic guitar received by my microphone interferes my voice, and disturbes the pitch correction. The pitch correction is ok, when I use my electric guitar, when I use headphones.During rehearsal with an Amp the pitch correction is also disturbed.

If your pick up system also contains a microphone, it could pick up your voice. You could try a feedback buster on your acoustic to prevent this.

[Boisdelac]

I don't think that I need a feedback buster for my acoustic guitar. But I will try to reduce the acoustic guitar pickup volume to check if the guitar picks up my voice, and if this messes up the  VE-500 pitch correction.

What type of microphone are you using? Is it cardioid or omnidirectional? Also s condensor mike is more sensitive to ambient sound than a dynamic mic.

[Boisdelac]

I use a Beyerdynamics Soundstar MK2. Very old of course. Concerning the Beyerdynamics information it's a supercardiod microphone. I will test everything with my other microphone, which is a shure Alpha 57.

Many modern Acoustic guitars incorporate both a piezo bridge as well as an internal condensor Microphone - some have separate volume or "blend" control to disable the internal microphone for best results with Vocal harmonizers / pitch correctors  at live gig

[Boisdelac]

There is only a piezo pickup in my acoustic guitar. In the meantime i think there is a crosstalk from my guitar into my vocal microphone an the pitch correction tries zu correct my voice and my guitar....which is impossible.

[Boisdelac]

As I already suspected... the reason is crosstalk... when I play my acoustic guitar plugged in and don't sing, the strange noises are there too. In this case, if I turn off my microphone, there is silence. To clean things up a bit, I entered a value of around 80 for the Noice Surpressor in the VE 500. Now it´s ok but for life gigs i will not use the pitch correction.
