I would like to step input not only note but also velocity.
For example,
Write mode
shiftt+n
(numpad)6 <-change duration
C (upper)80 <-Velocity 80
D (upper)90 ← Velocity 90
E (upper)100 ← Velocity 100
or
Play mode
When clicking velocity edit box,
(numpad)/ select all (same Ctrl+a)
(numpad). velocity input and play note and select note moves next and select all velocity edit box
(numpad)* velocity input and play note and select note moves down and select all velocity edit box
(numpad)+ Velocity up
(numpad)- Velocity down
or
Note select
V 80 ← input Velocity 80
