Meta Events to CC or Note Velocity

Hello,

 

I am an arranger and realize MIDI mockups. Was wondering if anyone might write a script that converts Meta events to CC events or note velocity? I would like to be able to choose which Meta event and value to CC# and value or velocity and value. Hopefully this makes sense. Post questions.

 

I will compensate, no problem.

 

Thanks!

 

Tom

Scripter doesn't see meta events. you will have to do that with the environment.

 

What meta events are you working it? In some cases you may be able to get Scripter to watch automation values and respond to those, but not actual LogicPro meta events.

I assume Scripter doesn't see meta events in Logic 10.4.8?? If it does see script below. If not, thank you for your help!

 

These are the meta events I want to work with:

 

Dynamic markings meta events, pppp through ffff.

 

Meta event# 0-ppp to CC2 value 10 or note velocity 10

Meta event# 1-pp to CC2 value 20 or note velocity 20

Meta event# 2-p to CC2 value 35 or note velocity 35

Meta event# 3-mp to CC2 value 50 or note velocity 50

Meta event# 4-mf to CC2 value 65 or note velocity 65

Meta event# 5-f to CC2 value 85 or note velocity 85

Meta event# 6-ff to CC2value 105 or note velocity 105

Meta event# 7-fff to CC2 value 115 or note velocity 115

Meta event# 12-ffff to CC2 value 127 or note velocity 127

Meta event# 13 pppp to CC2 value 5 or note velocity 5

 

I had this script written several years back, might this be edited for my purpose.

If you markup the script code with the

 tag it will be a lot easier to read.  

 

Scripter does not see meta events.

Thank you!

Also you might want to consider copy and pasting your script into the following javascript beautifier...

So what I would recommend is that you learn more about the environment. The environment can detect and convert meta events . You might be able to use a simple environment transformer to convert meta events into some kind of CC event. Then Scripter could detect the CC event and do whatever you want to it in a more complicated manner. You could also do the whole thing entirely in the environment, but I view that as more complicated. Use environment just to transform meta events into some kind of CC event... and then in scripter you can use those CC events to do whatever you want to do to the notes entirely in the non-meta realm.
