Hi,
I have this example in my fork of fluidsynth (I haven't changed the original API):
I'm rendering PCM in memory and writing to disk. You can change it to render entirely in memory or whatever you need.

Hi,
The reverb and chorus do not work at all using libfluidsynth release
2.1.0, either in my app or in QSynth.
However they work perfectly using the release 2.0.2 (Same code, just
re-linked the apps).
Am I missing something?
I was happy to see there are new reverb and chorus in 2.1.0, but it
looks like they do not work.
The fluid_synth_set_reverb*() API calls return FLUID_OK
I followed the API calls with the debugger, and the functions do not
exit prematurely.
I am on Ubuntu 18.04 LTS, if this can be relevant.
Did I hit a bug?
Regards
Pascal

Hi, Pascal
>The reverb and chorus do not work at all using libfluidsynth release 2.1.0, either in my app or in QSynth.
Here the reverb and chorus work using the fluisynth application console. Did you try this application before any other one ?

The best starting point for you would be to use the fast file renderer example:
http://www.fluidsynth.org/api/index.html#FileRenderer
However, instead of using the file renderer's
fluid_file_renderer_process_block(), you would directly call a
rendering function of the synth, as mentioned in this small section:
http://www.fluidsynth.org/api/index.html#UsingSynth
