RNBO Delay Noise on FL Studio

Henrique Lorentz's icon

Hello everyone! I'm using RNBO to develop a delay effect with C++ export and JUCE. It works perfectly as standalone and in Ableton, but different testers on FL Studio have shown me that there's a lot of noise when turning the feedback up. I found an old post on this forum mentioning the same issue, with no fix. I attached a video from a tester.

FL studio has the ability to use variable buffer sizes when processing audio. It could be that this is an issue here. I would recommend first trying to set the fixed buffer size option in the plugin wrapper. If it is still an issue, please contact us via support with more details of your plugin so that we can assess.

Thank you, Joshua and Mihail. I did fix the problem by switching my delay~ and feedback~ objects for a gen~ based delay, but I will try both solutions and report back with my findings! Cheers.

RNBO works with vector try to export as fixed vector size (there is option in export bar). FLS is strange daw which constantly changing the audio buffer size that can introduce clicks and CPU overload with some plugins
