5 Essential Logic Pro X Piano Roll Tips

You can do so much more with Logic X's Piano Roll than just drawing in MIDI note events. Darren Burgos shares five of his favorite Piano Roll/MIDI editing tricks here.  

The Piano Roll is used to graphically edit and display any recorded MIDI you've played into Logic, or it can be used to step-enter notes directly. You can also edit the controller data you play like pitch bend and modulation here. In this article I'll show 5 Piano Roll tips to make working with your MIDI recordings easier.

Tip 1 - Make All Notes the Same Length

Click a MIDI region in one of your songs and press the P button on the Mac's keyboard. This opens the Piano Roll window. When playing bass lines, programming drums, or recording chords and melodies you'll often want all the notes to be the same length to achieve a tighter feel. Select the notes you'll be processing by either selecting them with the mouse, or press Command-A to select all. First, click the end of a region to adjust its length. Then hold Option-Shift while you're adjusting. All selected note ends will snap to the current grid setting.

Tip 2 - Make All Velocities the Same

Now while you're at it, you might also want all MIDI velocities to be the same. More often than not, velocity'"how hard you played the keys'"is assigned to an instrument/drum's volume, so adjusting this will level out the sound's overall volume. This can be great for stabilizing a kick or a MIDI recorded piano/keys part. Again, select the notes to be leveled first, press the Option key, then drag the velocity slider up and down.

Tip 3 - Quantize Notes to Fit Your Song's Key and Scale

Although I prefer using Region Parameters (at the top of the Inspector), you can easily quantize notes and even 'quantize'

Thank you for #4! I use this feature a lot.

Great to hear! Yes I do too. Actually I go back and forth between nudging by tick when I'm working on the feel of a MIDI part, and by division when I'm working out the actual part.

I like this kind of piano, the installation will not be very troublesome, we are using roll up piano
