MIDI Voice Controller is an audio to MIDI converter that converts the pitch of your voice (or musical instruments) into MIDI note signals. The app detects one pitch at a time (i.e., melodies only). MIDI signals can be used to control synth apps running on the same iOS device, or on other networked devices and computers.

MIDI Voice Controller is Audiobus compatible. Sends MIDI on channel 1.

Major delay and poor accuracy

The reason they recommend using this for drawn out string parts is because there is a major processing delay (500ms?) between the time you sing and the time the [sometimes] corresponding note is triggered. The Fourier transform they use is picking up upper harmonics (which is why it says the timbre of your voice affects the quality of the output). There is also very high sensitivity to error, so unless you sing with the pitch of a newly tuned piano, it's not going to be a workable app.

Great idea. The execution needs help.

Great support!! Working!

After getting some specific instructions on how to get this to work with Windows, I am now able to use this. The support has been responsive and obviously helpful, as it now works. It is definitely a work in progress, but the big potential is there.

Does not return a usable midi signal

Iphone 6 iOS 8.1 will load the app but the midi signal that is outputed is complete noise. Unusable. Showing several non related notes (non harmonics) over several octaves when one pitch is sung.
