Invert. Reflect. Play.

Breaking down the physical barriers of traditional keyboard layouts. MidiReflect electronically mirrors MIDI mapping across standard 88-key instruments for left-handed pianists, symmetrical music education, and boundary-pushing performance.

Purpose & Design Philosophy

Engineered to Remove Physical Constraints

Although MidiReflect can be enjoyed using a standard 88-key layout, it is primarily designed to break down the physical barriers of traditional right-hand-dominant keyboards.

Ergonomic Left-Handed Piano

For centuries, acoustic and electronic keyboard architecture has catered strictly to right-handed dexterity. Left-handed players often face biomechanical hurdles when mastering complex melodies with their non-dominant hand. MidiReflect seamlessly inverts note mapping across the board, allowing dominant left hands to lead melodies naturally on standard digital pianos without requiring expensive custom instruments.

Face-to-Face Symmetrical Instruction

Music teachers can instruct left-handed students with unprecedented clarity. Rather than standing uncomfortably behind a student or reaching across the keyboard, a teacher can sit directly opposite using Reflect Mode to demonstrate hand positions. The visual geometry mirrors the student’s perspective perfectly, creating an intuitive, ergonomic learning environment.

Expanded Performance & Dual Registers

MidiReflect opens up entirely new avenues for musical experimentation. Performers can execute one-handed split-register voicing, instantaneously toggle between standard and reflection layouts, or configure hardware splits where high and low registers sound in tandem with a single physical keystroke. It also solves complex spatial arrangement constraints in stage and studio rigs.

Eurorack CV/Gate Polyphonic Dispatcher

For modular synthesizer enthusiasts, MidiReflect features an integrated 4-voice CV/Gate polyphony engine. Incoming chords from live play or loaded MIDI files are automatically distributed across independent MIDI channels configured for CV/Gate converter modules. Choose between First Touch dynamic allocation or Left-to-Right pitch ordering.

Visual Architecture

Physical Layout Preserved, Mapping Inverted

Under Reflect Mode, active notes retain their physical on-screen key positions while the transformed note is dispatched to the sound engine, MIDI output port, and Eurorack channels.

Note Mapping Inspection

Close-Up: 88-Key Note Reflection Symmetry

Compare the key note labels directly. MidiReflect mirrors note numbers across the mathematical symmetry axis: Reversed Note = 124 - Note.

Standard Keyboard Layout (Ascending Low → High) Pedals: Soft (L) • Sostenuto • Sustain (R)
Standard 88-Key Note Labels from A0 to C8
← A0 (Low Bass • 27.5 Hz) D4 (MIDI Note 62 • Symmetry Center) C8 (High Treble • 4186 Hz) →
Reflect Mode Inverted Layout (Mirrored High → Low) Sustain (L) • Sostenuto • Soft (R)
