Will this work?!?!?

Mixer has preamps.

The one-piece "adapter" at Radio Shack would do the trick, since it has a step-up transformer inside it. The adapter in the picture wouldn't, since it's just an adapter. You can make an adapter with any two connectors, but the chances of it being useful are slim.

In this case, the problem is that mic level is something like 20-40 dB lower than instrument level. Could be more depending on the mic, but let's say it's 40 down since it makes the math easy and proves the point. Every 20 dB step corresponds to a 10:1 voltage difference, so a mic that's 40 dB below instrument level produces 1/100 the voltage of a guitar pickup at its terminals. A step-up transformer of the right ratio will step up the voltage and impedance while stepping down the current, allowing you to use a low-Z, low-V mic with a high-Z high-V input circuit.

I had a feeling that would be the problem. The notes from an electric guitar pickup are virtually pure harmonic-series sine wave from which the fundamental should be easy to determine, being the largest and lowest-frequency component; human voice is more complex with glottal puff rate in the 120-240 Hz range (male and female, respectively), so the same math probably wouldn't work, at least well.

Just simply picking up all the noise in the vocal mic will make it impossible to use a mic as a midi source. The g2m would try to trigger on every snare hit or bass note. Now i could see you using a throat pickup for this but it would look pretty silly to have a throat pickup on stage.

If you put a expander on the mic and could get your volume way over the noise then you could use a modulator to convert the voice to pure tones and then to the converter. But as mentioned this would be a complex setup for a very limited range.

As for the comment before about not having enough lines it was because you didn't have any notation to how everything was going to work. I could have assumed you were going to run your vocal mic into your guitar amp or something. That's why i asked the questions to get some more clarity on what you were doing and why you were doing it.

I see, theres a youtube video of a product review for the sonuus g2m it shows a guy using it with a mic. So I understand its monophonic device and shouldnt be able to work with voice but the video shows otherwise. Do you think all the background noise of playing with a band would just make it not be able to read and convert a single note.

Yeah having all the extraneous noises on stage will cause your converter to read false positives. So while it might work most of the time for your voice, as long as you put a preamp in line with it, it will probably trigger falsly when the noise from the stage reaches it's threshold. From what i understand of the device it actually has multiple thresholds which gives it dynamics. I would assume that the device always reads the loudest source so as long as you are screaming into the mic it would convert your voice. Of course when you pause, take breaths, or just stop the noise on the stage will trigger a lower threshold.

Now if you put enough processing on the mic before the converter you can improve your odds and lower the number of false possitives but by how much i don't know.

It's not my money so it's easy for me to say try it and see how it works in your environment. My guess is that it's not going to work like you imagine it will.

There are demos in controlled environments and then there is reality.

Thanks guys, Ill let you know how it goes.

Your mixer mic inputs are preamped.

EDIT: I clearly didn't read the second page... missed the earlier post.
