| Summary | 0006524: ZynAddSubFX LV2 weird stutering issues | ||||
| Description | I've noticed a very strange behaviour of ZynAddSubFX in Ardour 4.1. Notes played and internal parameter changes seem to be processed with a slew limiter and a sample-and-hold unit generating a slow changing sound with stutter and heavy note quantization. I've captured a video: https://www.youtube.com/watch?v=pomFPzqN05s | ||||
| Additional Information | I'm using KX Studio. I used Zyn a few months ago with Ardour and such stuff didn't happen. | ||||

with DSP load > 90%.. (indicator top-right) things like this are to be expected. those are x-runs. There are probably some other heavy plugins in your session or CPU heavy jack applications running. Increasing the jack buffersize may also help. For everything over 80% DSP load you'll be out of luck for any reliable audio/midi performance (note that jack display the average not the max). |

I don't think that's the cause, becasue in the same session I'be been playing MDA Piano with an external USB MIDI keyboard for hours without hearing a single dropout. There are no audible clicks, as there are with xruns. I know that recordings not always capture xruns as they sound out of the soundcard, but in this case, the sound captured in the video is verbatim. I listened to it after uploading. |
