    Best way to create midi from audio
    Hi. I am in the process of layering/replacing drums and will need to create midi from some of my drum tracks. Here is the ways I found so far: Region to new sampler track: - Pro: You can use transientmarkers as base for creating midi (which is the way I prefer) - Con: All velocities gets the same (?) Drum replacement / Audio to Score: - Pro: Midi velocities based on the transients - Con: You can not generate midi based on transientmarkers. You need to use a threshold setting, which means you get a hard time if you have a lot of "spill" in the track. So, is the above observations right? In my dream world I would like to base the midi on transient markers and get velocities based on the transients. Is this possible? All the best! -

    Hi Mastergod, You are correct with the pros and cons on the two methods of midi to audio functions in Logic. Unfortunately Logic does have some limitations when it comes to converting audio to MIDI. Take a read through Jay Asher's article on converting audio to MIDI with Logic: [url]http://www.macprovideo.com/hub/logic-pro/audio-to-midi-shootout-logic-pro-9-vs-melodyne[/url] The problem is trying to extract both the transients and velocities from the audio file. Maybe Melodyne is the tool you're looking for?

    Hello, this article doesn't seem to exist. I think Melodyne is the best and I've heard that the new version can do polyphony. I took out the free trial and spent time using the tools. You can edit the different parts of a note. My question is about using Audio to Score in other things than drums. I tried it on Bass using various Basslines and got different results. I did notice that it will definitely pick up and transcribe fret noise but that could be taken out by some sort of noise filter. I think the answer to the dream product is to design a system that transcribes the fundamentals and skips the overtones. I don't know the settings make that much difference but I could be wrong. 100 ms is a tenth of a beat at 60 and a fifth of a beat at 120. I am interested in what settings others use for various instrument ranges such as Bass and different types of input signals.
