MIDI is the UART serial communication with 31,250bps.

BPS 31250:?CHR$(#90,60,100);

This is the random rhythm machine program. It's very simple!

10 LET[0],36,38,43,50,42,46,39,75,67,49 20 BPS 31250:S=0 30 SRND S 40 FOR I=0 TO 7 50 ?CHR$(#99,[RND(10)],1); 60 WAIT 10 70 NEXT 80 K=INKEY():IF K S=K 90 GOTO 30

#99 means the tone of rhythm 10ch. The numbers of line 10 are volca beats's 10 sounds. (UART0 is a command to ignore sending via UART)
