Push 2 : very good product

Good material quality, live 9 comes with not one but three different tools for analysing audio and generating MIDI clips containing notes derived from the original material. In fact, audio-to-MIDI has been in Live for a while in the form of clip slicing, whereby an audio clip is taken apart and converted into a MIDI clip playing a Sampler which contains fragments of the original audio. However, the audio analysis used in this process is rudimentary, and audio transients or warp markers are the only information used. Live 9's new analysis features dig deeper into the audio material. As you'd expect, the functions are extremely sensitive to the quality and accuracy of the source material, and you'll almost certainly have to do some cleaning-up work with the resulting clip. To test the harmonic capture I started with a MIDI clip playing piano, froze the clip to generate audio and then did the harmony-to-MIDI conversion. Apart from a few spurious high harmonics, the result was pretty faithful to the original, although these were ideal test conditions. I also threw three minutes of Debussy from my iTunes library into the system, and the result was a pretty impressive transcription, with only the occasional obvious wrong note.My attempts to capture a whistled tune as a MIDI melody worked after a fashion, although it insisted on rendering all my F-naturals as F-sharps: I suspect the source material was to blame. Drum-to-MIDI conversion seemed less useful: a lot of my tests ended up as snare-only, or all three sounds layered at once, and since the resulting output is so simple in terms of sound palette, you're probably better off just playing by ear or sequencing it directly. As the disclaimer goes, your mileage may vary!
