My UJAM plug-in stops playing after a while. What can I do?

Dropout

Some users have reported that their UJAM plug-in stops working properly after a while and that they lose sound output. While we haven't been able to reproduce this behavior, we are still working to find a cause.

If you know certain steps how to reproduce this behavior, please let us know!

Here are possible workarounds.

1. Delete and undo

You can reset the plug-in by deleting the current MIDI track or the whole track of your stopped playing instance and undo directly afterwards to release the plug-in from this. 

2. Use MIDI Drag & Drop

In this case we recommend using the MIDI drag & drop feature instead of triggering the phrases with a single MIDI note. Read more: How to use MIDI Drag & Drop

3. Buffer size/ CPU

We suspect that this problem might be caused by high CPU utilization, users reported that this problem occurs less on devices with higher CPU performance.

We recommend setting the buffer size higher so that the computer processor handles the information more effectively so that it will take fewer system resources and it’s less strenuous on the computer processor.

Increasing the buffer size can help to stay more stable for the plug-in. Some users reported that it could help to set the buffer size higher than at least 500ms to prevent the issue. 



It depends on the DAW and your device's performance for the best buffer size
and you will probably need to test different settings to find what's best on your system.

Note that when recording, we recommend choosing a lower buffer setting for quicker information processing to reduce latency. But when it comes to editing, mixing and playback, we recommend a higher buffer setting to prevent errors.

4. Close & open project or restart DAW

If the previous steps don't help, you can always re-open your session or re-start your DAW (this is normally not necessary).

Additional Troubleshooting

Sometimes the plug-in might stop working because of some MIDI errors that can also cause a dropout when triggering phrases.

• Try to start and end on bar boundaries (on the first beat of a measure)
  
• Try to avoid overlapping MIDI notes (the playing engine can only play one phrase at a time)
  
• If you have a repro case (steps that cause the issue) please start a support ticket to provide your info to UJAM support.
