Textquencer is a unique MIDI sequencer where you type sequences as text.
Notes are represented by letters (C, D, E, F, G, A, B) with accidentals (# for sharp, b for flat).
Simply type note names like 'C#', 'Eb', or use R for rests in your sequence.
Add numbers after notes to specify octaves (C4, F#5) and durations (C4:1/8 for eighth notes).
Use special syntax for expressive sequencing: < for decreasing velocity, > for increasing.
The - symbol creates legato notes for smooth transitions.
Create chords by enclosing notes in brackets like [C4 E4 G4].
Set global parameters like tempo, key, and scale at the top of your text.
The text editor provides syntax highlighting to make your sequences more readable.
Create multiple patterns to organize your compositions.
Each pattern can have its own text with independent settings.
Switch between patterns during playback for dynamic performances.
Copy and paste patterns to quickly build variations on your sequences.
Use scale-relative notation with roman numerals (I, ii, iii) for chord progressions.
All notes can be automatically quantized to the current scale.
Choose from over 110 built-in scales or create custom scales.
Textquencer can visualize your sequence on a piano roll for better understanding.
Textquencer operates as both a standalone app and an AUv3 MIDI plugin.
Save and recall your text sequences as Audio Unit presets.
Control pattern switching and other parameters via MIDI CC or AU automation.
Use MIDI input to record notes into text format for editing.
Textquencer offers its core components on Github.
They are all shared libraries for iOS, macOS and tvOS platforms, written in Swift.
A music theory library with Note, Interval, Scale and Chord representations in Swift enums.
Fully customizable and editable knob with rotary, horizontal and/or vertical gesture recognition.
