Music is more fun when accidents happen.
Fantamidi helps you rediscover inspiration through random, musical MIDI generation.
**Fantamidi** is a step sequencer & synthesizer plugin that supports creative music production.

Create 16-128 step loop sequences easily with an intuitive piano roll interface. With 18 scale types (major, minor, pentatonic, modes, blues, etc.) and root note settings, you can create beautiful melodies without music theory knowledge.

The dedicated bass area allows you to edit and generate basslines independently, and the automatic pattern generation feature (4 variations) helps you quickly shape your ideas. Random note generation and pitch randomization features help you discover new ideas and inspiration.

The built-in synthesizer features 4 waveform types (sine, triangle, square, sawtooth) and an ADSR envelope. Customize your sound freely with pitch shift and volume control.

Practical features include 8 preset slots, Undo/Redo functionality, and MIDI export (main/bass separately). Available in VST3/AU formats for use in major DAWs.

It’s been notarized by Apple, so use it worry-free!
Windows version might be next.
The Windows version is ready now!

I’ve always preferred making music with my own hands rather than relying on AI. But in reality, creating music can be tough. When I play the keyboard, my usual habits show up, new inspiration doesn’t come, and sometimes I can’t think of where to take the track next.

Music-making often needs “happy accidents” and moments of inspiration more than overthinking — and ideally, I wanted a tool that could make the process a bit easier. That’s why I created a plugin called Fantamidi.

The moment a randomly generated combination of notes—matched to your chosen scale and key—clicks with you, your inspiration and energy can suddenly surge.

Fantamidi is a tool designed to bring back that excitement and joy of creating music.**
