Welcome to your Harmonizer

Computer · Step 1

Install the plugin

Your Harmonizer comes with the plugin and the app. Download them on your computer and run the installer.

Windows: the installer isn't signed yet, so you'll see "Windows protected your PC". Click More info, then Run anyway.

Computer · Step 3

Open the app

1. Open MTG MIDI Harmonizer from Applications (Mac) or the Start menu (Windows). On a Mac, click Allow when it asks to use the microphone.
2. Type in your licence key.
3. Click Audio & MIDI. Pick your audio interface, then the input your mic is on.
4. Plug in your Harmonizer. The app picks it up.

Wear headphones. Laptop speakers feed back into the mic.

Computer · Step 3

Ableton Live

Quickest way: open my template and everything's already set up.

Setting it up yourself:

1. Settings → Plug-Ins: turn on Use VST3 Plug-In System Folders, then Rescan.
2. Audio track with your mic on it, Monitor In. Drag MTG MIDI Harmonizer onto it and type in your key.
3. MIDI track: From = your Harmonizer, To = the audio track → MTG MIDI Harmonizer. Monitor In, record-armed.
4. Settings → Link, Tempo & MIDI: your Harmonizer's input, Track and Remote on.

Computer · Step 3

Logic Pro

Quickest way: open my template and everything's already set up.

Setting it up yourself:

1. New Software Instrument track. In the Instrument slot: AU MIDI-controlled Effects → MTG → MTG MIDI Harmonizer. Type in your key.
2. At the top of the plugin, Side Chain = your mic input.
3. Record-arm the track (the R button).

It isn't an Audio FX. Putting it in an Audio FX slot gives Error -50. That's normal for this kind of plugin in Logic.

Computer · Step 4

HX Stomp · Step 2

Load my HX preset

Plug it all in

2. HX Stomp output → your interface or PA (TRS).
3. Harmonizer → MIDI host box (USB-C).
4. MIDI host box → HX Stomp MIDI In (5-pin MIDI).
5. Power on the HX Stomp and the host box with their 9V adapters.
