Logic 11.1

[liho26]

In the Logic 11.1 OsTiRus, Osirus doesn't play midi events.
Mac Os Sonoma 14.5
Logic Pro X 11.1. (latest)

Any ideas?

Are you running in Single or Multi mode? Do you send midi on the correct midi channel? We never experienced anything like this

Hi there.
Thank you for your reply. Let me describe the situation in detail.
On Sonoma I updated Logic pro X to version 11.1. On new project I added some native synths from Logic and an osTirus.
Everything worked perfectly.

Then I tried to add a new instance of the osTirus synth while Logic was playing a track. Logic said "system overload" and stopped playing. After this, the second instance stopped playing MIDI clips. But the first instance was still able to play the previously added MIDI clips.

When I open Piano Roll and press piano keys, I'm able to hear osTirus sound. But when I press "Play" button in Logic, osTirus doesn't play midi notes.

I thought the problem might be in Sonoma and upgraded Mac OS to Sequoia yesterday. The problem has not gone away.

More to say. When I create new midi clip on new osTirus instance, synth doesn't play midi. When I copy any midi clip to an osTirus track, osTirus doesn't play midi. But! If I copy midi from previous instance of osTirus that was created before "System Overload" message, second instance of osTirus plays midi! WTF?

I tried to create a new project in Logic Pro X 11.1. And I got the same problem. First instance of the osTirus and next added instances doesn't play midi notes.

Mode is "Single". Midi channel is correct. Both the Osirus and OsTiRus synths have the same problem.

And another additional info. I have a licensed synths from Korg. And I have the same problem with the Korg synths.
