Hi together, very interesting and productive community here. I have just skimmed over the source code of your midi operation system and noticed a possible issue: file: mios_isr.inc function: IRQ_UART_Rx_Hlp_GetCMax This function is used to evaluate the number of databytes expected for a particular message type. For message 0xF3 (song select) the function seems to return 0 expected databytes, whereas, according to the midi specification, the message should have 1 databyte. So long, carry on with your nice project! latchup
