Hello,

I’ve been running Frescobaldi (2.0 up to 4.0.1) with Qsyntth/Fluidsynth 
installed by MacPorts on an Intel MacBook Pro and never had a sound problem. 
Could this problem be related to Rosetta (an Intel CPU emulator running on 
Apple Silicon)? I mean, synthesizer software compiled for Intel CPU and running 
inside Rosetta, while Fresobaldi is running natively on Apple Silicon, or vice 
versa?
