피아노 롤#
The piano roll is the main editor for editing MIDI regions, and is displayed when a MIDI region is selected.

Additional Controls#
The piano roll contains the following additional controls.

Piano roll controls#
Piano Roll Keys#
These are the keys corresponding to each key found on a piano.

Piano roll keys#
Clicking on each key allows you to listen to it, much like pressing a key on a real piano.
A label for each key is shown on the left side of the black/white keys, in addition to any highlighting (if selected). See 강조하기 for more information.
팁
The vertical zoom level can be changed by holding down Ctrl and Shift and scrolling.
MIDI Arranger#
The MIDI arranger refers to the arranger section of the piano roll.

MIDI arranger with notes#
The MIDI arranger contains MIDI notes drawn as rectangles from their start position to their end position. Zrythm will send a MIDI note on signal when the start position of a note is reached, and a note off signal when the end position of a note is reached.
Editing inside the MIDI arranger is covered in Edit Tools and Common Operations.
속도 편집기#
There is another arranger at the bottom of the MIDI arranger for editing the velocity of each note.

Velocity refers to the force with which a note is played. Each instrument handles various velocities for the same note differently, but generally a higher velocity will result in a louder or stronger note. Velocities are useful for adding expression to melodies.
The velocity of each note is drawn as a bar, where higher means a larger value. Clicking and dragging the tip of each velocity bar allows you to change it.
팁
You can also edit multiple velocities at once by selecting multiple MIDI notes before editing a velocity bar.
The 램프 도구 can also be used in the velocity editor to ramp velocities.

Using the ramp tool on MIDI note velocities#
MIDI Functions#
MIDI functions are logic that can be applied to transform the selected MIDI notes.
The following functions are available.
- Crescendo
Gradually increase the velocities of the selected notes from low to high. Used to create a climax.
- Flam
Create additional MIDI notes right after the start position of each selected note. This is usually used on snares.
- 뒤집기
Reverse/flip the selected notes horizontally or vertically.
- Legato
Connect all selected notes so that they play smoothly.
- Portato
Similar to legato, but leaves some space between the notes.
- Staccato
Make the selected notes short and punctuated.
- Strum Up/Down
Shift the position and velocity of notes that start at the same position (chords) to simulate strumming, like when playing guitar.
할 일
Add illustrations.
참고
Some of these are not implemented yet.
In the future, it will be possible to implement custom functions using user scripts.
