Audio plugin that lets you use MIDI to pitch-shift via delay to turn unpitched audio into melodies

Melodrumatic

Overview

Melodrumatic is an audio plugin that lets you "pitch-shift" via delay (i.e. the Doppler effect) to turn unpitched audio into melodies. Controllable via MIDI or mouse :)

Available Formats

VST3, AU, AAX, Unity

Installation

Download the latest version of Melodrumatic from the releases page, then unzip and place the individual files into the appropriate plugin folders for your respective DAWs (or Unity!)

For Mac, this usually means:

VST3  -->  ~/Library/Audio/Plug-Ins/VST3
AU    -->  ~/Library/Audio/Plug-Ins/Components
AAX   -->  /Library/Application Support/Avid/Audio/Plug-Ins
Unity -->  [YourProjectName]/Assets/Plugins

And for Windows, this usually means:

VST3  -->  C:\Program Files\Common Files\VST3
AU    -->  Not supported :(
AAX   -->  C:\Program Files\Common Files\Avid\Audio\Plug-Ins
Unity -->  [YourProjectName]\Assets\Plugins

For Unity projects, install the plugin (audioplugin_Melodrumatic.bundle on Mac, audioplugin_Melodrumatic.dll + audioplugin_Melodrumatic_UnityScript.cs on Windows) into [YourProjectName]/Assets/Plugins.

Usage

For DAWs

(NOTE: The screenshot examples are in Ableton Live, but the steps should be relatively similar for any DAW you use; currently the plugin has been tested with Ableton Live, Logic Pro X, and REAPER)

1. Insert Melodrumatic as an effect on the track whose output you'd like to pitch-shift (this can be either an audio or a MIDI track).

2. Create a MIDI track.

3. Route the MIDI track's output to the track that Melodrumatic resides on...

... and specifically to Melodrumatic.

4. (optional) If you have an external MIDI controller, assign that as the input to your MIDI track so that you can control Melodrumatic live!

For Unity

1. Insert Melodrumatic as an effect onto the desired Audio Mixer (the plugin will show up as audioplugin_Melodrumatic).

2. (optional) Right-click parameters and select "Expose parameterName to script" in order to control Melodrumatic through scripting!

NOTE: Since the Unity plugin normalizes parameter values to a 0-1 range, in order to treat the Delay Time parameter as MIDI notes you'll need to re-scale the values. This can be done by quantizing values to steps of 0.0078125 (i.e. 1/128).
