    AudioStretch might be worth a try. About Midimorphosis, does that work more accurately than the Pitch to Midi feature in Infinite Looper & Aleph looper? I've tried a lot of experimenting with Aleph Looper's Pitch to Midi and the results are all over the place. Even in a quiet room with a tap on the table generates a bunch of random notes.

    Wondering if Midimorphosis' audio file processing works a little better?

    For something like a tap on a table, Voxkit would be way better. It's looking at the profile of the transient more than the pitch. Honestly I doubt anything is going to work reliably. There are too many variables. You might get some interesting results, but consistent results I doubt.

    Actually, it looks like Logic Pro X can analyze and create a midi track from flex pitch data. I haven't tried yet, but the demo videos I've scanned look like I might be able to do what I'm describing using a combination of a heavily eq'd file the better isolates the parts I'm most interested in, then using flex pitch data analysis for the conversion to midi, then remix everything within LPX.

    I wonder if this flex pitch audio to midi functionality is also in Auria Pro?

  • Update: Tried this out in Logic Pro X and it actually works fairly well if the soundscape isn't too dense. Haven't played with heavy eq yet.

    Noticed that Auria Pro has Audio to Midi too... but it's to "MIDI Transients". I'm guessing that's different and basically just isolates sharper beats with no pitch detection?

    Nicely done.

  • AT vocal app actually triggers MIDI notes.

    I couldn't get this to play. Maybe it's using flash and doesn't work on iOS? Will desktop later. Dig all of RedSky's stuff.

    Thx, but not finding it in the AppStore. It's called "AT Vocal"?

  • By the way... although it looks like what I'm trying to do has been many times before, it's working out well so far.

    Took a fresh recording I did with very distinct birdsong at around 5AM in Mindo, Ecuador (only time I could get a recording without a motorbike or chainsaw in the distance).

    Brought that into Logic Pro X, used Flex Pitch, saved the conversion to midi notes to it's own track, then played around driving some Alchemy synths with the midi and mixed with the original birdsong. Sounds spectacular!

    I'm now moving that midi file back over to the iPad for more experimentation on the iPad too since I've got more toys there. :)

    Would it be possible to achieve this effect in a production environment by aggressively filtering the audio in Auria Pro and then using the groove to MIDI function (or whatever it is called)?

    It's also possible to modulate pretty much anything in WOW by specific frequency triggers.

    I don't know. I didn't know that about WOW. I've only had it since the last holiday sale and have mostly used presets. Will look into that too.

    Regarding the groove to MIDI in Auria, I'm not familiar with that. I did read in the manual that Auria has Audio to MIDI too, but it's "Audio to MIDI transients". From what I read, that's not really the same thing I'm able to get with Flex Pitch in Logic Pro X. I think the Auria Audio to MIDI is more like the Voxit app that @wim mentioned, where it's only converting the beat to transients for percussive use.

    From what it looks like so far, I think it's much easier and more acurate, etc. to do this conversion in LPX using it's Flex Pitch feature. I could be wrong, but I don't think there's anything in iOS that even coms close to how well Flex works for this sort of thing. I'd be happy to be proven wrong though. :)

    Not sure how flex pitch works but my suggestion is to crank up the eq to extreme levels on the frequencies you want to catch, kill any freq ranges that you want to ignore, run audio to midi transients and see what happens. Might get something interesting/usable in a rhythmical way.

    Yes, I'm going to try that too. The results from Flex Pitch in LPX were very detailed and complex. Fairly accurate too based on visual inspection of the wave form.

    I didn't EQ the file before though, and I think that would made a big difference in LPX too. Only after my first composition, did I discover that there was STILL some f@#king motorbike noise in the distance in my source recording. I'll need to go back and at least EQ that out anyway.

    I'd post my first composition in Auria, but it fell apart quickly because I was triggering an arp that was a bit too funky and it all turned into a chaotic mess before I had to throw in the towel. The second attempts in AUM were much better, but I was having trouble sync'ing the play button to launch my source recording in AUM and the play button in Genome that was playing the midi file. Will try again later, but I heard enough in each attempt to warrant further experimentation. Somewhere between musical and random generative.
