Editing basics

Entering notes

The easiest way to enter notes in Reflow is to use the numeric keys of your keyboard.

Notes are inserted at the exact location of your cursor, which is the blue square you can see on your staff.

This cursor can be moved using the arrow keys of your keyboard, or simply by clicking on the staff at the desired location.

Tablature Input

If your cursor is located on a tablature staff, you can use the 0-9 keys to enter frets. This will add or modify notes in tablature.

Standard Input

You can enter a note on a standard staff by pressing the 0 key.

You can delete a note located under your cursor by pressing the Delete key.

Drum Input

Drum input is a little different, the cursor location has no effect on input. Numeric keys from 0 to 9 are mapped to Drum elements. Pressing a numeric key will enter a drum note and move the cursor to the correct location.

  • 0 : Bass Drum (BD)
  • 1 : Hi Hat Closed (HHx)
  • 2 : Snare (Sn)
  • 3 : Ride cymbal (Rd)
  • 4 : Hi Hat Opened (HHo)
  • 5 : Side stick (SS)
  • 6 : Low Tom (LT)
  • 7 : Crash Cymbal (Cr1)
  • 8 : High Tom (HT)
  • 9 : Mid Tom (MT)

Pressing the same drum element again will remove a note.

MIDI Input

If you have a MIDI device (keyboard, drumkit ...) plugged into your Mac, you can enter notes directly by playing them on your instrument.

Notes and chords you play on your MIDI device are added automatically to the beat where your cursor is located.

After a successful note entry, the cursor moves to the next beat, allowing you to continue entering notes.

There is no real time MIDI entry in Reflow at the moment, entry is a step by step process.

You can check that your MIDI device is used by Reflow by opening the Preferences dialog.

Virtual keyboard


Reflow has a virtual keyboard that allows you to view notes and enter them.

Keys are highlighted according to the notes located below the cursor.

To enter a note, simply click on a key.

If you press a key that already contains a note, this one will get removed.

If the keyboard is not visible, you can open it with the menu View > Show Keyboard.

Virtual fretboard


If you're working on a tablature staff, Reflow allows you to use a virtual fretboard.

Notes are highlighted as they should be played on a real guitar.

You can click on a fret/string to enter a note.

If you click on an existing note, it will be removed.

If the fretboard is not visible, you can open it with the menu View > Show Fretboard.


The keypad takes a different layout depending on the staff you're working on.

On a tablature, you will see it turn into a numeric keypad to enter frets.


On a standard staff, you can enter notes and accidentals directly.


On a drum staff, every button correspond to a single drum element, mapped directly to your numeric keypad.


A second pad is available using the Alt button.


Manipulate beats

In Reflow, a beat could represent a note, a chord or a rest.

Beats are time divisions of your measure, and can contain zero, one or more notes. A beat with no note is effectively printed as a rest.

You can change beat duration using the +/- keys on your keyboards.

The note value can also be changed directly using the buttons in the palette.

Note values

Add and insert beats


These two buttons allow you to create a new empty beat (a rest actually) right after the cursor, or right before the cursor.

Delete a beat

Delete beat

Using this button, you can remove a complete beat from your measure.

Split beat

Split beat

With the Split Beat tool, you can divide a beat in two exact beats with a shorter note duration.

Using this tool on a quarter note will give you two identical eighth notes.

Try it on your drum beats, and see how much time this simple tool will save you.


You can select multiple contiguous beats in the same measure with a Left Click and Drag on your mouse.

You can also select without your mouse. Hold down the Shift key and move your cursor with the arrow keys. Selection will be extended in the corresponding direction.
