I want to quantize not only tempo but velocity, since the first hit on the hi hat by MIDI is too strong. I can do it bar by bar, using the MIDI editor. But is there a way to select and quantize multiple tones to the same velocity?
Holding down ctrl while clicking the mouse on the specific note (or group of notes if you drag the mouse) will select as many midi notes as you require. Velocity is then shown and if all are the same value then reducing the velocity by say 20 will reduce the velocity on all the notes by 20.
Unfortunately if one of the notes you selected had a velocity of (say) 30, it will reduce to 10.
