Enter the Matrix at Hyper-speed!

Many Logic users are probably using the Matrix (or "piano-roll") editor as the main way to graphically edit MIDI data. The screenshot below shows some notes recorded into a MIDI region.

In adition to inserting, deleting, moving and changing the length of notes, you can use the "Mute" tool to mute and unmute individual notes or selections of notes, and you can use the Velocity tool to change the velocities (the small line in the middle of each note is its velocity).

This way of editing note velocities though is fiddly, and not very clear, especially when editing drum parts with lots of short notes, so let's look at another way to display our note velocities.

The Matrix editor has an inbuilt Hyperdraw function, which works in much the same way as the Hyperdraw display on a region in the arrange window. Here we are selecting the "Volume" controller, which is the displayed along the bottom of the window. You can use this to create and edit all kinds of MIDI controller data - volume, pan, pitch bend, modulation, and so on. You can switch between any of these, or any other MIDI controller, but using the little down arrow flip menu to the left of the Hyperdraw lane.

You can make the Hyperdraw display bigger or smaller by dragging the dividing line between the note display and the Hyperdraw display.

This Hyperdraw has an extra feature - you can set it to display note velocities. Click on the menu again, and select the bottom value - "Note Velocity". Now you can graphically see the velocity of each note displayed in the matrix window, and drag the velocity value or each note, or selected notes, up and down.

That's a much more comfortable way of editing your note velocities!
