What is Midifier?

Midifier is an audio plugin. It converts monophonic audio tracks to MIDI data in real-time. Using Midifier, you can control your MIDI devices with your own instrument or voice, rather than using the MIDI keyboard.


Midifier is a VST plugin for PC/Windows. You can use Midifier with any PC sequencer or audio editor which supports DirectX or VST plugins.

If your host supports DirectX plugins only, you need a VST-DX adapter or wrapper plugin which lets you use VST plugins in DirectX hosts. See more about this issue in the section Using Midifier With....

Also, if you don't own a sequencer or audio editor you can still use Midifier with freely downloadable host programs. See the section Using Midifier With... .

Only the standard sampling rates of 44.1kHz and 48kHz are supported. Let us know if you intend to use Midifier with higher, 88.2kHz and 96kHz rates.

How does it work?

Load some audio material on one track in your sequencer. Then set up Midifier and a MIDI track for output and press the play the button of your sequencer. It's that simple.
Midifier transforms the audio to MIDI notes on-the-fly. Your melody will be played back with the instrument you set up for the MIDI output track.

Depending on what sequencer or audio editor you use, Midifier can be used in two ways:
