Hi

Using the 8 track playback in Mainstage 2 for live work and have just discovered there is such thing as a vocal harmony processor.

They are mainly linked to guitar or keyboards to get the actual key, but I wondered if anyone was using one of these linked to the key of the backing track.

If not, can you simply preset the song key.

Also, are there any latency issues in routing the vocals through such an item?

    The TC Helicon products do this sort of thing very well. They depend on a guitar (or there is a keyboard model also) input for key/chord detection, and a vocal input. You could run an audio out of your audio interface into the key/chord detection input from your MainStage backing track, as long as the backing track was "pure" so that the device could detect chords easily. There would be minimal latency .... check out the videos on their website.

    Thanks

    Found the Voicelive Touch which appears to do what I need.

    Interesting product. I would find it cumbersome to use my fingers to control things while playing guitar, and prefer footswitches. But I suppose it would work for some....

    I have a VoiceLive 2 --- it is quite wonderful. I know nothing about the Touch version although it's supposed to have exactly the same algorithms.

    I am having good results here with Antares Harmony Engine.

    I use it in performance from within MainStage. It will add harmonies within a selected key and style, and it will also give me the the harmonies I play on a MIDI controller!

    I'm on keys, so it will sit nicely on the top.

    You can however add a footswitch if you're a guitarist.

    Now this is interesting.

    Can you put the plug in in the vocal channel strip?

    If so, doesn't it require the key of the backing track or can you pre program the key and just slot in in the vocal channel strip?

    Two things to watch out for when using vocal harmonizers for live performance:

    1. Hardware does not introduce appreciable latency. Software MAY introduce enough latency to make the product unusable for critical live vocal use. Try before you buy. I tried a demo of Mu Voice which had pretty low latency and is for live use, but there is a big learning curve.

    2. Harmonizers rely on having a pure, monophonic input signal. When playing live, your mic will be picking up everything around you (PA, instruments), which may confuse the harmonizer unless you sing right up on the mic in a quiet environment, with no loud instruments playing. Try before you buy. Some hardware harmonizers do a good job of limiting and filtering the garbage out (like the TC Helicon stuff), others not so good.

    These two reasons are why you often see online demos or reviews performed with users wearing headphones, or just adding harmonies to recorded vocal tracks.

    Isn't "hardware" today essentially a dedicated CPU running some software?

    Some hardware is. Much signal processing in hardware can be achieved via analog circuitry, versus intensive math-based computations required in digital signal processing. Electrons are faster than the little guy sitting in your computer with a calculator. If the hardware employs DSP and microprocessing, speed level differences between the hardware box and pc/mac software is often due to low level processor code execution versus high-level.

    But you are right, the line tends to get a little blurry these days between some hardware and software. Try before you buy!
