Unlock your music potential. FormKey is the first music suite that helps you become the musician you've always imagined being, just by using it.
INTRODUCING FORM
Form is a new way to read and create music. Notes become shapes. Octaves become colors. Duration becomes a simple to read fraction. You can learn to read and play music in minutes. FormKey is the first release of the Form notation language, an open licensed music language designed to create instant music literacy. With the goal being to become a standard you'll see everywhere.
THREE MODES: CREATE, LEARN, AND CONTROL
• Create mode gives you a 16-track sequencer built on the classic drum machine workflow, modernized for today. Use your own AUv3 plugins or the three we built in to create full tracks from the ground up.
• Learn lets you play and read your way through classical pieces while Form teaches you exactly what the music is doing, note by note.
• Control turns FormKey into a MIDI controller for your external workflows, so it fits right into the setup you already have.
THREE BRAND NEW AUv3 PLUGINS
• Tone is a fully interactive subtractive synth that makes synthesis make sense. Every knob and connection is something you can hear and understand, so the architecture of a sound stops being a mystery.
• Wave is a file-based sampler that lets you chop audio samples from your device, designed to make Slicing, and rearranging samples feel effortless instead of technical.
• Patt3rn is a suite of modeled instruments curated to provide users with high quality options when looking for go to sounds every sequencer needs.
• All 3 work in any host, so the instruments you learn in FormKey come with you wherever you go.
SCALE MODE
Reshape the keyboard to any of 26 scales, so every note you play stays in key. Choose from:
• Major and minor: Major, Natural Minor, Melodic Minor, Harmonic Minor
• Modes: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian
• Pentatonic and blues: Major Pentatonic, Minor Pentatonic, Blues
• Symmetric: Whole Tone, Whole-Half Diminished, Half-Whole Diminished, Augmented Hexatonic
• World and exotic: Hungarian Minor, Neapolitan Minor, Byzantine, Enigmatic, Hirajoshi, In Sen, Kumoi, Iwato
We've refined the interface across the app, making FormKey easier and more enjoyable to use.
Every feature in FormKey is free to try. In celebration of our launch, $14.99 unlocks everything for the life of the app. We hope you love it as much as we do.
