MIDI Keyboard Latency Problem with Logic X (Big Sur)

Hi All,

I last posted on this forum 6 months ago as I noticed the following problem:

1) When I create a new software instrument and play a MIDI keyboard part live, I experience an annoying degree of latency that means I can't play the keyboard live (only draw in MIDI notes.....) When I first open a Logic X project the latency is non-existent, but only for about 30 seconds, and then the latency is extremely pronounced. I checked my Logic buffer size and it is 64, so I don't imagine this is the issue?

I did not get an answer to this problem 6 months ago, but observed there were other Logic X users also experiencing this issue (with some saying it could be an issue with their OS e.g. Catalina, Big Sur etc)

I have now finally upgraded to OS Big Sur, hoping that the latency issue would be addressed by updating Big Sur together with the Roland A-300Pro's latest compatible driver.

However...... the same problem still exists and it is driving me insane!

I contacted Roland 6 months ago and they couldn't help.

I also sent a 'user message' to Apple about the issue to ask them to address it in future Logic X updates, but there was no improvement when I last installed the recent Logic X update.

Can someone please help!

Kind Regards,

Mr Rock

Can someone please help resolve these issues?
