MTU Key Changer

[ddouglass]

Hardware electronic components designed and set for specific pitch change will not cause harmonics (which are what cause the vibrato effect) or if they do a filter can be added to remove it.
As an explanation harmonic frequencies tend to be slightly phase shifted (out of phase with the primary signal) and this is what causes the vibrato/echo. I may have a tin ear, but I do know electronics.
When you are trying to change a pitch by altering the frequency fed to a standard sound card designed for a wide range of frequencies then there is no way to filter out those harmonics completely. This is why I say Electronic Key Change will always be better.
Currently I wouldn't expect them to look at this at this time as they are trying to get a new release out to fix and stablize 4.06 even more first. Maybe in the future they can take another look at it.

That would be your opinion since I have never used their program I wouldn't know whether theirs is totally clean or not. Iwould suspect though that their built in equalizer would be helping with that.
I am not saying it couldn't be better in Hoster but I have never had any complaints from any of my customers about it being that bad.

Well all i can relate to is my experience with sound, and key controllers i have used. I have been a musician for going on 35 years now. And i can only say that when i lower, or raise a key in the Hoster software. It changes the quality of the music. Seems one would have to be almost tone deaf not to hear the wobble, and loss of fidelity of sound.

I sure would hate to have to start plugging my computer out, through my key controller, then to my mixer. I just love the quality, and stereo seperation my Hoster system gives me. I have this one sweet little gal, who has a garbled voice like a coal miner. I think it's from years of smoking. And i have to lower everything she sings. It's a pain, but she's a paying customer to. Anyway, i can live with it, but my comment was, the MTU key controller as i said, "Leaves Much To Be Desired". Not complaining, just making an observation. {Oh, the little gal with the hoarse low voice, keeps trying to date me}

In reference to this, I too have noticed the issue but not quite the way you describe. I notice that it doesn't sound right with certain songs and certain key changes. One song may have a harmonic problem with minus 2 but sounds fine with minus 3. Another may be just the opposite. I, too, have ruined my voice after 30 years of smoking. The songs I used to sing on stage 5 nights a week seem to be just a step out of range for me now. The good news is, I am quite good at Barry White songs now

The live Keychanger has always been poor no matter what computer i have used with a slight warble sound when used, When writing a file using keywrite i have never had a problem with the new sound file. My current Hp computer has realtec onboard sound and the software has it's own karaoke function with key changer. I use this if I take my small system out and works fine. For my bigger venues i use a seperate nikkodo keychanger. It would be nice to have it all in one package though.

Key control in a software package must not be an exact science. I just wish MTU would spend a little more time on the issue is all. Seems some kj seldom use a key changer, why, who knows. Maybe they just figure everyone should sing the song as it's written, and ignore the red faces on some struggling to try and make pitch. I couldn't get by a night without my key controller. If i see some of my regulars struggling to sing in key, then next time, i suggest they let me drop it down...could you imagine some of my older singers trying to sing a Vince Gill song without a key change? i cringe at the thought....

I can't imagine any older singers would try it knowing that they couldn't sing in Vince's pitch anyway.
