2018-JUL-26: Tested MIDIDRVR.OBJ on real hardware - the code to change the Annunciator works. The Negative Logic does not work yet.

|
||||||
|
|

GIVEN midi out circuit can play a chord, and driver is loaded at $9000
|
||||||
|
|
||||||
|
WHEN you enter the following Applesoft BASIC program and run it
|
||||||
|
|
||||||
|
10 P=36868: M=36867 : REM P=ADDRESS TO POKE MIDI BYTE, M=CALL TO MIDI OUT DRIVER
|
||||||
|
|
||||||
|
20 FOR N = 60 TO 72 : REM NOTE NUMBERS FOR MIDDLE C THRU ONE OCTAVE ABOVE MIDDLE C
|
||||||
|
|
||||||
|
30 POKE P,144: CALL M: REM 144 (0X90) IS THE MIDI MESSAGE FOR NOTE ON
|
||||||
|
|
||||||
|
40 POKE P,N: CALL M: REM FIRST DATABYTE OF NOTE ON MESSAGE IS NOTE NUMBER
|
||||||
|
|
||||||
|
50 POKE P,64: CALL M: REM SECOND DATABYTE IS VELOCITY OF KEYPRESS (0=127)
|
||||||
|
|
||||||
|
60 FOR DE=1 TO 250: NEXT : REM DELAY LOOP
|
||||||
|
|
||||||
|
70 POKE P,N : CALL M : REM USING RUNNING STATUS - MESSAGE IS STILL NOTE ON, BUT NEW DATABYTES
|
||||||
|
|
||||||
|
80 POKE P,0: CALL M : REM VELOCITY OF 0 TURNS A NOTE OFF
|
||||||
|
|
||||||
|
90 NEXT N: REM REPEAT FOR EACH NOTE IN CHROMATIC SCALE
|
||||||
|
|
||||||
|
|
||||||
|
THEN you hear a chromatic scale played on your MIDI instrument.
