<![CDATA[Does everyone turn HISE_COMPLAIN_ABOUT_ILLEGAL_BUFFER_SIZE off?]]>I'm seeing FL Studio complain about illegal buffer sizes. Claude investigated and said (my summary):

  • FL Studio is know to give plugins their own buffer size, regardless of the main Buffer Length setting
  • This was an issue in HISE for a while back in 2022 and Christoph added the UI-blocking warning message
  • Handling of illegal buffer sizes has since been fixed in HISE, but the UI-blocking message was never removed
  • It can be disabled with HISE_COMPLAIN_ABOUT_ILLEGAL_BUFFER_SIZE=0
  • Apparently, the audio is not affected and the instrument functions properly

So, does everyone just set HISE_COMPLAIN_ABOUT_ILLEGAL_BUFFER_SIZE=0 and get on with their lives?

Is it time for this preprocessor to default to 0 instead of 1?

FL Studio is so temperamental

Ugh, indeed. And not really something I can ignore.

I just did a user survey and FL Studio users are 8%, third largest after Live 61% and Logic 14%.

I just tested Rhapsody in FL and it didn't show the UI-blocking message. I wonder why?

I don't see it either. FL Studio is so temperamental, I have another user who gets this

I'd like to do some more tests.

I wonder why?

If you haven't set HISE_COMPLAIN_ABOUT_ILLEGAL_BUFFER_SIZE=0 in your export then I would expect it to show.

I already confirmed the 'Use fixed size buffers' toggle fixes the issue, but I don't particularly want to send my customers to a 'Troubleshooting' page to fiddle with settings, and also be shown this message:

I just tested exported AU and VST with HISE_COMPLAIN_ABOUT_ILLEGAL_BUFFER_SIZE=0 and they both seem to operate fine. That test, along with Claude's assurance that the issue has long-since been dealt with in HISE source, is good enough for me.

In fact recently a user sent me this message

Rhapsody kept crashing in my FL Studio until I toggled the "use fixed buffer size" on. Now it's smooth and fast.
