Advanced Logic Pro MIDI Questions Answered

  • by
A composer sits in front of his studio synthesisers. He is frustrated. The captions reads "why is my midi not working?"

My name is Paul Andrews and I run a small company called Audio Support. Every day, I remotely connect with musicians all over the world to help them with their studio equipment. 

Logic Pro Expert - Remote from London UK

20th March 2025

This afternoon I connected with a composer in Suffolk, England with a large collection of hardware synthesisers in their home studio. They are using Logic Pro on an Intel Mac and the system is running smoothly. Last week I solved a problem for them that involved the arpeggiated data coming from a Moog Muse and how it is recorded in Logic Pro and then transmitted back to the Muse.

This week, my client and I connected again to answer some questions about advanced features in Logic Pro.

How do I fix the length of MIDI notes I’ve recorded in Logic Pro?

I explained to my client how to do this using the Functions Menu inside Logic Pro’s Piano Roll Editor

How do I edit modulation data recorded into Logic Pro?

I showed my client that there were a number of ways to edit modulation data (and any other CC information sent from his synths) but the simplest method that I would use would be to use the lower lane of the Piano Roll editor. I showed my client how to find this and the various tools that were available for MIDI CC editing.

Is it possible to make the patches on my synths change automatically when I load a Logic Pro project?

I showed my client how it is possible to set bank and program information inside Logic’s External MIDI instrument plug-in. My client found this very helpful as he would no longer need to manually set ten patch changes on his synths when he changed which song he is working on.

Really friendly and helpful. Quickly identified a 'red flag' in my set up that was causing my problems, and took the time to look around at my settings, explain why things worked in certain ways, and followed a step by step re-import of some audio to check for problems. Ended up smoothing a whole bunch of wrinkles for me!

Absolutely exactly what I needed. Paul was just so helpful in breaking the mysteries of why some of the functions in Cubase 14 pro weren't working for me. So friendly and knowledgeable. Thank you so much for your time. I will definitely come back to you if I need any further help.
