Useful but unreliable

I want to like this app - the need for such is self-apparent. But it’s just plain unreliable and jittery, and the time-locked experiences I have with the free version don’t make me want to plunk down $10 for more of the same. Would buy if improvements to detection algorithm and output data streams were made.

An amazing real time audio to midi tool!

I needed to feed a midi converted pitches from my woodwind in order to feed a visualizer. This is straight forward, took me less then 5 minutes to configure everything and accuracy is very good! I used a small condenser microphone that fed input in A2M. In Ableton Live I just used provided virtual midi port and it works! These audio to midi tools aren’t widely available, but this one gets the job done! Thank you!!!! Other one I was trying was Doubler 2 but that is designed for a voice and on a woodwind it was making mistakes.

Good idea

Like the concept but frankly I have found it rarely produces good quality translation of audio into midi even with simple input such as pads. With more complicated material I have never produced good quality midi . The app needs a further round of development ment in my opinion

Not readable

How do I even use this? I can’t even create a new track. I don’t get how this works at all. Until I can use it properly, I’m keeping this review at 1 star. Also the website doesn’t help
