![]() So if you have the money and want to do things quick, go with Mixed In Key 5. Mixed In Key has a very intuitive user interface and with version 5 it is very fast on a multi core system. The GUI is not very user friendly and the application is slow. Rapid Evolution however, is a lot more work to configure and set-up. The pro for Rapid Evolution is that it is free and Mixed In Key isn’t. Although this test set is too small to draw any conclusions in there. First of all, they both give bad results although Rapid Evolution seems to be a little bit better. If I would need to recommend a software package I would nominate both Rapid Evolution 3 Beta and Mixed In Key 5. I have already experienced with this before and I’m getting better in it, so over time I will probably be able to do this also much faster. People with high musical skills probably can do this a lot faster. But say you have to wait for the software too. ![]() First of you have to actually attend to manual key detection as where the software could be analyzing songs while you are away. When looking at time required by software and manual key detection there is a big gap. Most of the times the key is nearby or there is only a Major Minor mismatch. I use the song key found by the analyzing software as start point. ![]() After that I check the results by hand with my Ableton Project. For example, I use the software for initial key analysis. But the software isn’t a complete waste of money. So the data from the software can’t be trusted at all. I think I can conclude that also the data from Beatport is far from valid and that it looks like they use one of the commercial available software programs. But also the conversion from Wav to Mp3 produces different results which might be not audible for me but are of impact on the algorithm used by the software. For example, the tracks I used come all from a CD which could have undergone additional mastering to make all songs sound good together in terms of dB level. This can of course be caused by small differences between the songs I used and the songs they have. There doesn’t appear to be a perfect match between their results and one of the results I had with the software. It is hard to say how Beatport acquires the information. I wasn’t able to find all songs back at beat port, but most of them. That genre has more songs in Minor key.īeatport shows the song key also for their tracks. But if you play trance music, it is the opposite. As rule of thumb that is true for this genre of music. If you look at these results, you might say that most music is always in Major. The problem seems to be that the software has a lot of trouble determining if a song is in Major or Minor. If we are a little less strict and say that a compatible key is also valid, the results improve much: What does this mean? If we look very strict to the correct key results, it doesn’t look good at all: So here are the results shown with Camelot notation: I’ll might blog about this another time, but for those interested, on the website of Mix Share (Rapid Evolution) is a description on how you can find the song key by ear. So using Ableton, two VSTs and a small MIDI keyboard I went out searching for the song key the old fashion way. For example, I do know how to use a computer and software to find the correct key of a song while trusting my ears. You get where I am! Great, let’s continue.īut there are also things I do know. ![]() I even wrote down what Camelot key corresponds to the actual keys on my MIDI keyboard. Third I always use Camelot notation because I don’t know the wheel of 5ths. Second, I don’t know how to read notes and definitely can’t hear them. First of all I’m not a musician and know nothing to only a very little about music theory. If you are a musician and have experience you can probably hear this or find out by playing the notes along on a piano. So we’re going to need to do this our self. For example the sheet music might say a song is in Major C but the song might be performed in different key. It might be correct but doesn’t have to be. However, they don’t have sheet music or the song key for all the tracks and the source of the information is unclear to me. The challenge is to get the actual key of the track.
