Key mapping for pitch screen wanted

One thing: This isn't a pitch-increase. This is a Playback Speed increase.

Describing it in terms of pitch increase is actually incorrect.

Well, this is both speed and pitch increase. So describing it in terms of pitch increase is not "incorrect" but rather "half correct" :-)

Then this should be discussed separately


--- Quote ---Hmm, isn't the percentage exponential too?

I think no. Correct me if I'm mistaken.


--- Quote ---If I set the Pitch to 150% I expect that the song is played one and a half time faster.

That's what I expect. But 150% is not the same as 6 semitones (half of an octave). One semitone means multiplying frequency by the factor of 2^(1/12). 6 semitones up mean multiplying by 2^(1/2), i.e. changing the frequency to 141.4% of its initial value.

Changing the pitch in 0.1 semitune steps makes no sense IMHO since this is not a widely used term. A percent (or promille) is better here. But a semitune is a well established term in music.


--- Quote ---As you can see, there is realy no need for percentage.

Well, one could argue about this. It would be possible to toggle the display mode -- in % or in semitunes. This would be separate from pitch change mode. But this would also be a separate patch.

Llorean:
I think that as long as the method is simply increasing the playback rate of the file, the display should stay as percentage, since that's all it is. Play the file 112% faster, or whatnot, a value that is *particularly* useful for knowing when a file will end.

For example, if I have a 3 hour long trip, and a 3.5 hour long spoken audio program that I want to get the whole content from, I can increase the speed and while it will sound a little funny, I know what the minimal increase I need (minimal being ideal because of the issue of sounding funny) without having to convert from Semitones just to use time compression.

Once there's a pitch increase without playback speed then perhaps they should be considered.

Full ACK. But changing the speed+pitch in semitone steps is still a useful feature IMHO. The display can be always in %.

Llorean:
I have no objection to allowing semitone steps as an additional option. :)
