I like the duplicator effect built into my FP90 and was thinking of trying one of these with my Arranger. Anyone have any experience with it? Its TC Helicon so I know its a good quality.
Thanks for any info.

I love using a doubling effect just before I hit the harmony button to emulate the four freshmen approach. Like the way they do "Blue World"
The words "It's A" are doubled, the "Blue World ... without you" is full harmony.

Would you consider it good enough on its own if you didn't have a Harmonizer in your keyboard ?

No Bill. A simple chorusing effect doesn't do it for me. Instead, I'd opt for the Harmony Singer - much more useful.

Thanks Dave. I actually have the Harmony M but just looking for something very simple on/off and easy setup. Do you know how the Harmony Singer determines the correct Harmony without a Midi input ?

Background vocals are added by analyzing your incoming guitar signal and using your own voice to create professional-sounding harmonies.

Looks like there is an instrument input jack on the side of the unit ...

Yes, there is a 1/4" pass-thru jack that goes from your kb thru the SINGER then out to your amp. If you're not using an amp, it will still read the chords you play.

What could be easier than a single unit? Seems you already have a great device ... unless you're referring to plugging in AC AND midi , AND a mic - yeah, that's a chore. C;mon - buck up - it sounds great!

I know, its the being stuck around here so much and "What can I buy now" syndrome. Just lazy on my part but it is a few cables more to hook up. Thats the one thing I really wish the BK9 had, since it designed for the preforming entertainer, a vocal harmonizer.
thanks for the input.

thanks Tony Didn't look at it closly enough. OF COURSE its for guitar players. There goes my nice stereo sound from my keyboard so its out. Time to pull out the Harmony M again.

Harmony M is really good. I have one in each of my two setups. I tried Perform VK a couple of times, and it is really good, but I get along better with the older M.

Interesting. The VK is newer and looks to have soft feel buttons instead of footswitches so I'm curious why you like the M better. Just more used to it ?

NO, NO, NO .... you won't loose your precious stereo mix at all. You simply plug ONE SIDE of the kb into the unit then on to your amp/mixer. Stereo image is not affected, and the vocal is mono anyway.

The VK has more options, especially if you download extras, but with more bells and whistles you make things a little more complicated.
I use mine 99 percent of the time with one voice above, some reverb and the automatic e.q. processing.
I use a standard foot switch to bypass the harmony, the same as with VK.
It is easier for me to turn knobs if I want to change reverb or harmony levels than it is to press and hold buttons.

Thanks for the info guys. Thats what I was looking for . Saved me some money !

I used a Harmony-M for a decade - loved it. User friendly, inexpensive, and great sound quality.
