I go to "Built-in MIDI Synthesizer" on Synthesia as normal and select any .sf2 file, and while it can be heard, I have noticed the normal DLS music synth sound overlapping or playing on top of it, either masking or replacing the SF2 sound, but not all SoundFonts have this problem. I think it's an issue with the coding maybe or something else with the built-in MIDI synthesizer.
Game version: Synthesia preview-10.10.5933
OS version: macOS 12.5.1
System specs: Apple M1, 16GB of RAM, has 24-inch Retina display.
Either it's my iMac's MIDI synth, a bug within Synthesia which causes an overlap in synth sounds, or the built-in speakers.
Has anyone else found a bug like this on macOS?

When describing problems, always mention your OS and game version (shown at the bottom of the title screen).
If your keyboard has USB or MIDI ports, there is a tremendously high chance (>99%) it will work with Synthesia. See what you'll need on the keyboards page.
