Piano Booster on MacOS 11.2 & M1

[theotox]

To start by saying that the Catalina binary works on MacOS 11.2.3/M1.

What is not working is the Piano Booster with output to FluidSynth. ​
Midi in/out works fine.


I don't know if the problem I have encountered is related to the OS  or the type of CPU.

Has anyone any better luck with MacOS 11 on M1 ?
