Efektor Meloditron is a smart monophonic harmonizer that generates dual-voice diatonic harmonies according to your chosen key and scale, with per-voice panning and a low-pass filter for creative sound shaping.

Purpose
Efektor Meloditron is designed to add intelligent harmony to monophonic sources like guitar solos or vocals. Its smart engine analyzes your playing and produces two additional voices that follow your lead in real time, based on the selected key and scale, ensuring musical correctness rather than fixed pitch shifts.
The plugin’s workflow is centered on artistic control: you choose the key and scale, and the plugin generates diatonic harmonies that match your melody. This makes it a quick tool for composers and performers who want to enrich single-note lines with professional-sounding harmony without manual editing.
Key Capabilities
Meloditron offers a dual-voice harmony engine with a wide selection of scales and keys, allowing you to create from simple thirds to more complex modal sounds. Each harmony voice can be panned independently in the stereo field, giving you the ability to place voices exactly where you want them for a spacious mix.
A low-pass filter shapes the tone of the harmony voices, adding warmth or cutting brightness. The plugin also includes oversampling for clean audio reproduction and precise note tracking to capture subtle performance nuances. The single-screen interface keeps all controls visible, with no hidden menus.
Workflow
Start by setting the master key and scale that match your song. Then play your melody, and Meloditron will generate one or two harmony voices automatically. Adjust per-voice panning to spread them across the stereo field, and tweak the low-pass filter to blend the harmonies with your tone.
You can use the plugin standalone or as a module within the Amplifikation 360 environment, integrating it with amp simulators and effects in one chain. This makes it easy to experiment with different settings and hear results instantly, streamlining both studio and live setups.
Practical Applications
Use Meloditron to thicken guitar leads with harmonized lines, create vocal doubles for choruses, or add subtle texture to synth solos. It works well in songwriting for quickly hearing how a melody sounds with different harmonic intervals, and in arranging for building more complex parts.
For live performance, its smart nature means you can switch keys on the fly, while the straightforward interface ensures quick adjustments. The plugin is also featured in the Efektor Pitch Bundle, which includes additional pitch-shifting tools for broader sound design.
