Hi John.  Again thanks a lot for your upgrade toAdafruit_VS1053 which makes it compatible to the ESP32. 

I am just wondering what is special about the ESP32 that requires semaphores to be introduced? 

Assume we attach an ISR toDREQ.  The ISR gets the 32 bytes needed and sends that via SPI to the VS1053. Why will this model work on a Mega but not on an ESP32?
