I'm using a reface DX connected to an iMac running Big Sur 11.2.3 but can't sync with Soundmondo.
The browser is Chrome with full control of MIDI devices allowed and I even installed the USB-MIDI Driver V1.3.2-2 from the Yamaha just in case.
Any ideias what could be wrong?
You have the latest MacOS. Drivers are OS X (10) compatible, many thing do not work yet on OS 11
Apple has decided to use new chips and has changed many system functions. It is only a matter of time before all Audio and MIDI drivers will be tested and updated to work with the new functions. This is not the first time this has occurred in the computer music making universe. Just write it down somewhere for future reference: I don’t want to be the first one to venture into the new computer OS or buy the newest chipset. On the cutting edge there is always some blood.
Currently testing is proceeding. Compatibility is typically a few months later. Standby...
