Side projects I build for fun, learning, and real usage.
A professional iOS app that listens to your chords and automatically generates harmonic voicings for your melody — in real time, as you play.
Real-time detection of major, minor, 7ths, 9ths, sus, diminished, augmented — including inversions.
Separate in/out device selection, per-channel routing, 16 channels, wireless Bluetooth MIDI.
Route harmonized MIDI directly to any AU instrument. Works inside your iOS DAW.
Panic button, hold/latch mode, velocity filtering, presets — built for the stage.
I have always loved arranger keyboards.
There is something magical about them: you play a chord with your left hand and suddenly an entire band appears. Drums, bass, guitars, pads — all following your harmony in real time. For a keyboard player, it feels like having a musical ecosystem under your fingertips.
For many years I played with arranger keyboards and appreciated the elegance of that interaction model. It is incredibly powerful: simple gestures generate rich musical structures.
But over time my setup changed. As I started playing more with bands, DAWs, software instruments and live performance rigs, I slowly moved away from arrangers and toward synths, stage pianos, and MIDI controllers. And that transition was… a little painful.
Because while synths and stage pianos are incredibly flexible, they lack one thing arrangers do brilliantly: harmony awareness.
You can route MIDI everywhere, layer sounds, trigger clips, stack plugins — but if you want the system to understand the chord you're playing and react musically to it, things suddenly become complicated. I started missing that arranger-style intelligence. Not the styles themselves necessarily — but the idea that the instrument understands harmony and can react to it in real time.
That is where the idea for MIDI Harmonizer was born. The goal is simple: bring a bit of the arranger mindset into modern MIDI workflows.
Instead of building a full arranger keyboard, MIDI Harmonizer focuses on one powerful concept:
Play a chord on the left side of the keyboard and the system understands the harmonic context. Then when you play notes on the right, the plugin generates harmonized notes in real time.
All generated instantly and sent to your synth, DAW, or external MIDI gear.
