Hi,

I have a list of 30 midi-velocities that I want to map to 30 pitches, how can I do that without converting the velocities into symbols? Is that possible in OM (it is not for human players but for virtual instruments)?

(setf vel '(1 5 10 14 19 23 27 32 36 41 44 50 53 57 62 66 71 75 79 84 88 93 97 102 105 109 114 118 123 127))

converted to symbols it looks like:

(ppppp ppppp pppp pppp pppp ppp ppp pp pp pp p p mp mp mp mf mf f f f ff ff fff fff fff ffff ffff ffff fffff fffff)

which is not as 'smooth' as I want it..but make-omn seems to handle only velocity-symbol or am I missing something?

 

thanks for help!

What about floating point numbers velocity 🙂

(make-omn :length '(e = = = = = = =)
          :pitch '(c4 cs5 b3 c4)
          :velocity '(0.1 0.2 0.21 0.32))
=> (e c4 0.1 cs5 0.2 b3 0.21 c4 0.32 0.1 cs5 0.2 b3 0.21 c4 0.32)

thanks for the quick answer! So the floating point numbers velocity ranges from 0.1 to 0.99 or how do it relate to the 1-127 midi steps?

I want to create an as-smooth-as-possible crescendo from the lowest possible value to the highest over x steps..

Can you point me to some more information about 'floating point numbers velocity'?

In the velocity documents you find all the answers.

 

Example

All 127 velocities in floating point numbers:

(vector-to-velocity 0.1 1.0 (gen-integer 1 127) :type :float)
=> (0.1 0.11 0.11 0.12 0.13 0.14 0.14 0.15 0.16 0.16 0.17 0.18 0.19
