This probably been asked before but how do a find the key of the song I am sampling. Is there anything built in to FL studio to detect the key of the whole sample not just individual notes??
If not newtone then try pitcher or use https://www.audiokeychain.com/ or just press the shit outta ya keyboard (or piano roll if ya not got a keyboard) until a note sounds right through out the song
load the sample in edison. right click on the wave form, look for detect pitch regions and it will slice your sample into sections by their key. go to the first slice that has instrumentation in it and what ever key it is in thats your sample key. or just play piano to your sample
If you are really desperate for a way to find what key a song is in, you can download the free version of virtual DJ demo, load the track that you want to know what key it is in, and then it will tell you what key the song is in by the tempo readout.
