Piano roll scale

skdeish

Has anyone figured out how to get the piano roll to display a specific scale rather than the chromatic keyboard? You can quantize notes after they are drawn in, but I want to change the display to only show keys in a certain scale (like Ableton).

Algorithm of quantizing? Classic? What are the other algorithm?

Don’t think this is possible. I checked the manual and could not find any way to change scale or even reduce to “used” notes. I’m sure it’s not even possible on the desktop version. I will check that later.

Logic isn't Ableton 😉

There are 2: Classic and Smart. Excerpt from manual:

“The Q-Algorithm parameter in the Region inspector lets you choose from two quantization types for MIDI regions: Classic Quantize and Smart Quantize. Whatever type you choose is also displayed for the Algorithm parameter in the Note inspector and used when quantizing notes in the Piano Roll Editor.

• Classic Quantize quantizes MIDI notes to the nearest grid using the current Quantize settings and any advanced Quantize parameters.
• Smart Quantize works similarly to quantize for audio regions. MIDI events near grid positions (defined by the Q-Range setting) are analyzed. Based on a combined weighting of proximity to the target grid position and velocity, a reference point (“center of gravity”) is set for each group and moved to the target grid positions. All (nearby) MIDI events move proportionally to the reference point. How far each event moves is determined by the Q-Strength setting. Unlike Classic Quantize, all MIDI events keep their original order, similar to an audio region edited using Flex Time. This includes not only notes but all MIDI data types (such as Pitch Bend and Control Change events)”

There is a “collapse mode” in the piano roll within desktop logic, but it’s not available in the iPad version. Hoping they will add this in the future. It’s not Ableton, but it’s probably as close as we will get.
