In the following image you can see the gate working. We will use this to ensure that when we breathe or stop singing we will prevent the possibility of extraneous notes being added in our conversion. The next thing we can do is to put a gate right after the EQ. Also by having those EQ filters there we are potentially eliminating electrical noise and any miscellaneous background around us in the sample. We can improve our chances of pitch analysis correctness as well as rhythmic duration of the notes for the human voice in particular by adding in and EQ with a High pass filter set at the average fundamental of the human voice at 80 to 100 Hz and a Low pass filter set to 2KHz because we are not looking to track the harmonic content but just increase the effectiveness on our monophonic melody conversion. Another condition would be when there is not a clear difference between two notes for the algorithm to differentiate between. When there is lots of background noise or when the signal is very low sometimes the algorithm has difficulty. It will then analyze the audio clip and generate a new track beneath that sample with midi notes the algorithm deems are close to the original melody. If you are using a sample of your voice you would right click the sample like below and then click on ‘Convert Melody to New MIDI Track’. You can find the feature by right clicking any audio sample you have placed on the timeline in the DAW. The Ableton feature we will be focusing on today is the Melody to Midi conversion function. At least you can get closer to your envisioned idea faster. I have found this function is really useful for me when I want to brainstorm an idea quickly or when I might be in a place where a proper keyboard is not available. that still might be the right choice for you, but there is another way to take your voice or anything that has a pitch and convert it into midi notes in Ableton. If you have been wondering about how you can input melodies into Ableton and have been considering getting an external midi keyboard with drum pads etc.
