Hi there. I’m mapping my VST instruments and I’m trying to get a roll between two notes in a percussion instrument using multi-note tremolo.
The VST already has the sound of both notes so I only need to trigger the playback. sound one of the notes and leave the other one on the page without playback.
So far so good and the sound plays for half the duration of the note that is triggered, so now I can extend the duration using the key editor.
Now, what causes the audio crash is adding a note after the multi note tremolo and hitting play. There is sound for a fraction of a second and then Dorico works for a few seconds but the sound is gone. Eventually Dorico becomes unresponsive and crashes as well.
A couple of pictures of the percussion map and the percussion kit technique dialogue.
One more thing, I have experimented a bit and it seems that Dorico tries to create a multi-note tremolo with whatever note it can find after the note that has its playback disabled (this was the case when I tried with a piano instead of a percussion kit, the audio engine didn’t crash in that case).
Hi @Maester_Ludwig ,
would you please also choose from Dorico’s meny Help > Create Diagnostic Report which will create a zip file on your Desktop. That zip file contains also crash dumps that we are keen to have a look at. So please attach it to a reply here. Thanks
To provide a bit more information here: after some private discussion between Ulf, @Maester_Ludwig, and me, we have determined that Dorico is hanging, not crashing, and it’s hanging because the specific content that is being used inside Kontakt 8 is triggering a deadlock in the audio engine. We’ve seen this deadlock before, though it has historically been harder to reproduce. We are hopeful that the audio engine team will be able to investigate this problem in future.
Hi @dspreadbury and @Ulf , the audioengine team investigated and came to the same conclusion: occasionally, the Cajon doesn’t return from processing. The audioengine is waiting for the Kontakt thread to return and deadlocks.
I have contacted NI and provided them with the reproducer.
Interestingly, I could only reproduce with the Cajon instrument.
Hi all,
NI sent me a workaround which is supposed to avoid the freeze. I hope they’ll also work out a fix.
For now, this workaround might work for you:
Thank you for the update! I checked the proposed solution from NI and it does prevent the hang/freeze/crash It took me a few trial and errors until I noticed that I had to change change the parameters for both notes involved in the multi-note tremolo using the panel next to “Sent by Midi” but once I notice the issue went away.
The only issue with this fix is that the sound is a tremolo of the bottom note for half the first half of bar followed by a tremolo of the top note for the remaining half, but I guess it’s better than nothing. In any case thank you again!
