Is Key and Pitch the same thing?

My CDG player has a pitch slider. I just purchased another piece of equipment (mainly for the a/v switch and multiplex feature) and it has Key changes flat and sharp.

Was just curious is they were the same similar or ??

I'd personally use the keychanger on the other piece of equipment than either that is built into the CDG player as most of those effect the tempo as well as the pitch.

Thanks DannyG2006 the Pitch slider did seem to effect the tempo some, but wasn't sure. I didn't know if typically you had key, tempo and then pitch was a slight combination of the two.

The advantage of using the other piece of equipment is that you can change the key on any of the sources that are running through it.

In answer to the original question: The main difference between Pitch Control and Digital Keychange is that while Pitch Control will also change tempo - like it or not-( and possibly cause distortion), Digital Key Control will not. ( well, usually no distortion within at least 3 steps either way, anyway.)

Also, DKC is a bit more precise ( usually in 1/2 octave steps), while PC requires more guess work. If you have no desire for tempo change, DKC is usually the best bet.

Thanks JoeChartreuse

wow, 1/2 octave steps equal 4 tones.....those are big jumps.....

You are right, and that's one disadvantage of DKC vs Pitch, but at least you know where you are, as oopposed to pitch, which you kinda have to guess. Plus pitch changes tempo- lower is slower, higher is faster- without any control. Prefer DHC.

This is sort of on the same lines of the discussion -

I had a guy come in the other night and ask me if I could adjust by semitones. I didn't have a clue what a semitone was. I explained that I could adjust the key or tempo if he'd like. He couldn't explain what one was so when I got home I looked it up. Semitone is a half step.

According to some info I found on this unit (VocoPro KC-300 Pro), there is a 12-step DSP Key Controller to raise and lower the natural musical key by 2 full octaves.

On the display it's displayed from -8 (flat) to 0 (normal) to 8+ (sharp).

If 8 notes make an octave if I go up or down 1 am I'm changing the key by 2 half steps or one whole step right?

I'm pretty sure Joe has it wrong, the DKC works on HALF NOTES, not half an octave. Hence someone asking about Semitones. Each key change is a half-note. If yours goes up 8 keys and down 8 keys, it allows for a full octave of movement in the form of half and octave down or half an octave up. Refer to this chart for key changes:

Semitone? I thought that was not very good singers, semitone deaf

Tones......do re me fa so la ti do.......eight of the little buggers.....

When we use the key changer, we are really changing the pitch. Pitch and Tempo are two different elements, though some controls change both, by speeding up the media. Frequency is another element that tells you which pitch you are at. Though middle C, and the C which is an octave higher than middle C belong to the same pitch, the higher C has twice the frequency. I'm pretty sure that we call it the Key, as refferenced by the Keys of a piano corresponding to the pitches. I think scientists actually devide each tone into 12 semitones, though on a piano, you can only move by half tones.......feel free to correct me, I'm only human...

Since I only use one source, the key changer on compuhost is simple to use and I've had requests to use it lately. I've found I can use it to sing songs I could not sing otherwise with the very high parts such as Donny Osmond "go away little girl".

Or Boston "more than a feeling".

I actually prefer to sing the song in the original key and sing it higher or lower as needed.. *shrug*


Usually works out ok for me at least

But you are probably maybe 25-30 % of actual singers that know what they want.

I'm the same way, but it's nice to have the option for those that want it. I actually bought the piece of equipment for a/v selector 3 in 2 out. I couldn't find a rack mountable solution for less than the $100 I gave.



Or even know what they're vocal range is.

you have a point there. Most people don't even know what vocal range is..


As I said in my intro, I was part of a 100 voice choir, so I have a very small amount of music training..

Ahh... but how do you know that that's key it was originally written in? By the time the songs been covered by a number of artists or even the original artist it may not be close to the key the songwriter wrote it in. By asking the KJ to change the key to make it easier for you to sing, you may actually be changing it back to it's original key.
