Who makes a 100% octave drop pedal for microphone.  So far the only thing I've found that sounds good is the TC helicon nova system (but its too big).  I tried the TC play acoustic but it only provides a mix of octave down with the regular sound.  Is there a way to trick or modify the play acoustic to do this?  Or is there another pedal?  I need this to drop my tenor sax so it sounds like a baritone sax (sounds great on the nova system).

Hello, i have a Tc-Helicon Voice Prism Plus that is having an issue it has been stored for a good many years and when i turn it on it has power but the splash screen never changes from the intro message none of the knobs or effects work either, does anyone here no how to fix this issue or do the even still support or service this unit i have read about others that have the same issue with this same model, Is there a factory restore for this unit any ideas or advice would be apreciated

I stupidly plugged in the wrong adaptor in my TC-Helicon (an identical adaptor carrying 18v lying right next to Helicon adaptor carrying the correct 12v) and predictably the device powered on and immediately shut down. There was no burning, sounds or outward sounds of damage so I am hoping that it can be an easy fix if I take it into a repair shop (replacing a part)? Does anyone have any advice on this? What a stupid split second mistake.

I have used this product for years owned three, sorry to hear that this unit has been disconituned. they last me about 3 to 4 years as I perform mostly outside in a humid sea climate 100 shows a season. what happens is when the Harmony button is engaged it effects the guitar sound (Chorus like) also I have noticed recently that I am getting high pitch squeal/feedback when using the harmonies. My levels are all good. anyway to service this or is the unit going south?

I just got this unit and as mentioned by many reviews, the manual is really sub par. 

One thing I can't find is a definition of what certain parameters in the vocal section do. For example, what exactly do the following parameters do?

Porta - I have no idea what this does  

Smooth - What exactly is it smoothing?

Humanize (I get the general concept obviously, but what exactly does the unit do to achieve it)

Tuning (Just vs Barbershop?)

Gener - It has a range of -50 to +50

Hi.

I have a vocal track recorded in Ableton Live which I would like to process with the Voicelive Play GTX's hard tune effect, using a guitar track as reference for the harmonies. Please, could you help me with the proper set up and signal routing? 

Thanks
