MIDI always buffering on new Instrument Tracks

Whenever I create a new instrument track or load new presets in the virtual instrument like Kontat, Waves Finger Bass, Avenger etc and play on the midi keyboard, the instrument doesnt get any midi data at first, and then after about 5 seconds it starts playing those notes from the buffer

Hi,

Isn’t the track still loading the samples?

no. sometimes even the track was working ok, but I go to another track and then go back to that track it starts doing this issue again

Hi,

When you select the track, the Record becomes enabled automatically (by default). This means, the track switches to the real-time processing (no buffer and ASIO Guard is in use anymore). This might be the reason.

but this shouldn’t be happening.

I recently switched from windows 10, to Mac.
On windows 10 I had no such issues and I had Cubase 13 configured exactly the same way.

Hi,

In your original post, you were talking about the track creation. Later you were talking about other use case. Could you please clarify when exactly does the issue appear?

It happens when loading a patch in newly created instrument, or loading new preset patch.

Also this is what I just discovered:
Cubase works fine in Rosetta mode, this only happens in native mode

anyone ?

what can be the issue ?

Hi,

Again, if this happens only after loading a patch or the preset, are you sure, the patch has been loaded completely before you start to playing it?

yes it happens only (or i should say “most of the time” ) when loading a preset or patch and trying to play back a track with midi data or playing notes on the keyboard.
or when opening a template or project and selecting a track and trying to play it.
to me it seems like some kind of internal midi buffering issue, not sample loading issue.
I mean 2mb, 0.4mb, etc, of sample data cannot take 5 seconds to load. plus this issue never happened on my old windows 10 PC with SATA SSDs and slower dual channel ram. here I’m using MacBook with apple silicon where large sample libraries load about 2.5 times faster than on my old windows 10 pc, and CPU is much faster.
Also, if it was issue with sample loading, the notes just wouldn’t play until the sample data gets loaded. but here the midi data doesn’t get received to the VSTi3 instrument, which is causing the silence, and the other strange part is that after about 5 seconds it starts playing those notes from the buffer that I was playing on the midi keyboard in silence or the notes that were playing from midi track in silence. such thing never happens when waiting on sample to load.
It looks like Cubase is memorizing the midi data but not releasing it, and then after 5 seconds releases that midi data, and at the same time allows the midi to be transmitted to the Virtual Instrument.

Also when this happenes the master audio volume gets reset to full volume on the computer. So must be something to do with audio-midi driver in Cubase

I think I found the cause. I’ll do more tests to confirm.
