Even though the Duration menu in the Quantize dialog box is limited to 1/32nd notes, you can still quantize to smaller values by inputting a number of ticks into the Duration parameter. For example, if you’re using the default 960 ticks per quarter note for the project clock value (set in Preferences), then just type in 60 for the Duration to quantize to 64th notes. See pages 147 to 149 in SONAR X2 Power! for more information about the Quantize function.
