Fantamidi Free by Granvia is a free MIDI generator VST3 plugin designed to help producers create melodies and basslines without placing every note manually.
The plugin generates random MIDI patterns while respecting the selected key and scale. This keeps the results musical while introducing enough variation to break repetitive writing habits and generate new ideas quickly.
What Is Fantamidi Free?
Fantamidi Free is a step sequencer, MIDI generator and simple synthesizer for Windows and macOS.
Instead of generating completely uncontrolled notes, the plugin follows the musical key and scale selected by the producer. It can create separate melodic and bass patterns while keeping both parts inside the same harmonic framework.
The generated MIDI can be played through Fantamidi’s built-in synth or routed to another virtual instrument inside the DAW.
Scale-Aware MIDI Generation
The central feature is its scale-aware randomization system.
Choose a key and scale, then use the New or Add controls to generate notes. Fantamidi places the notes inside the selected musical structure, reducing the risk of producing completely unrelated pitches.
This can be useful for producers who understand basic music theory as well as musicians who prefer to work by ear.
Generate Melodies and Basslines
Fantamidi includes separate areas for main melodic material and bass notes.
This allows producers to create a higher melodic phrase and a lower supporting pattern from the same plugin. The generated parts can then be routed to different instruments or dragged into separate MIDI tracks for further editing.
A simple sequence can sound completely different when played through a piano, analog synth, pluck, bass instrument or cinematic library.
Drag and Drop MIDI Export
The generated MIDI patterns can be dragged directly from Fantamidi into the DAW timeline.
Once exported, the notes become standard MIDI data that can be edited, transposed, shortened or rearranged like any other MIDI clip.
This is one of the plugin’s most practical features. Fantamidi can provide the initial idea without forcing the producer to keep the original pattern unchanged.
Simple Built-In Synth
Fantamidi includes a basic synthesizer for previewing the generated notes immediately.
The internal synth is useful during composition, but the plugin becomes more flexible when its MIDI output is routed to another instrument.
Producers can audition the same pattern through several synths and sampled instruments until the musical idea finds the right sound.

Free Version Limitations
Fantamidi Free is a permanent free edition rather than a timed demo, but it contains fewer features than the commercial version.
The full edition provides more steps and controls, manual note editing and eight pattern snapshots. These features are not included in the free version.
The separate Fantamidi 2.0 trial is also limited to five-minute sessions. Producers looking for the permanently free plugin should download Fantamidi Free version 1.2.

Final Verdict
Fantamidi Free is a useful free MIDI generator plugin for producers who need fresh melodic and bassline ideas without relying on completely unrestricted randomness.
Its scale-aware generation, separate melody and bass areas, built-in synth and drag-and-drop MIDI export provide a fast workflow for electronic music production.
The free edition has fewer controls than Fantamidi Full, but it remains a practical creative tool for generating editable MIDI patterns inside Windows and macOS DAWs.
