How to quantize MIDI for Orchestral music production?

[steve]

is there any midi fx or function which allows doing strum?

Here’s how I do it for a four note chord- Macro: Logical Editor Preset A Logical Editor Preset B Logical Editor Preset C Logical Preset A: Context Variable = Note Number in Chord, 0 Position: Add 0.00.00.060 Preset B and C are the same, but Note Number increments by one, and ‘Add’ adds larger values. (the lowest note does not need to be moved.)
