Question

After a while, Logic Pro will start cutting off notes when playing in real time. Then while thats happening I have to force quit Logic.

Hello!

I am wondering if anyone else has experienced this. When I use logic, I usually will use my MIDI keyboard to play with headphones on to not disturb my neighbors. After a while of use, maybe 10-15 minutes, my notes will start cutting off after a second of the note playing. I can keep the key on the keyboard held down and nothing will happen. When I let go of the key, the note will ring for a split second, and I will hear the damper go down. Usually to resolve this I have to close logic and reopen it. For some reason, whenever this bug occurs and I try to close Logic, it freezes and I have to force quit it to get it to close. Is there a way to resolve this???

I know its not an issue with my MacBook because it did the same thing on my old MacBook.

For reference I'm using a 16" MacBook Pro M4, 24GB Ram, 512MB storage.

Which brand and model keyboard are you using? Make sure you're using a Class Compliant USB cable for your connections. Cheap USB cables will cause unstable communications and if it happened on your last computer I would bet on that instead of a bug in Logic. You can get a USB 3.0 Type-C to Type-B Gold Plated from Monoprice on Amazon for $11.

If you still encounter problems after making sure your cable is class compliant.

Try bypassing control surfaces under Logic Pro>Control Surfaces then open Control Surfaces>Setup and see if there are any devices listed. Remove all devices.
Navigate to Settings> MIDI> Reset Messages : Check boxes under external and software instruments settings for these control numbers and settings.

121

Aftertouch To Zero
Send Used Instrument Settings on Reset.

Restart your computer if that doesn't work with your MIDI Keyboard unplugged.

Plug it back in

3. Go to System Audio/MIDI Setup

Spotlight (CMD+Space) to Audio/MIDI Setup

Open MIDI studio (CMD+2) Click the refresh Arrow beside the Keyboard icon on the MIDI Studio bar.

Double check your IAC Drivers and MIDI Keyboard Settings. Open IAC Drivers - if you have more than one port listed, click the minus button until you only have 1. Check the device is online box. Click apply.

Hello EddieGrey,

I apologize for the late reply; I just got back from vacation. I have checked and the microphone was already set to standard, and changing it to voice isolation does not resolve the issue, nor does changing it back.
