Logic MidiFile Export Script ( LogicGenCsv.js)

 

Due to bugs I found in Logic's midi file export, I have created a little Scripter midi file exporter for anyone interested. See the following forum past about the bug:

 

viewtopic.php?f=1&t=147755

 

This Script will listen to a given channel and log output to the scripter window which is in a format suitable to create a midi file using the csvmidi utility.

 

Here is the script:

The results are much more accurate then LogicPros midi file export. Additionally I have provided options to export at many different PPQN resolutions. Going to a very large PPQN higher then 960 will result in even more accuracy exporting midi sequences out to midifiles closer to the accuracy they were recorded. Using a value lower then 960 can result in subtle PPQN quantizing which may or may not result in a slightly tighter groove.

 

Anyway, hopefully Apple may correct midi file export in the future to be both more accurate (higher PPQN as well as bug free from the deltaTime bug I have pointed out here.

 

Video Demo of the above Script to export midi file found here:
