Constructed MIDI to test pitch bend effects.
|
||
|
|
|
||
|
|
Findings:
|
||
|
|
|
||
|
|
* Doom ignores the least significant bit of pitch bend events
|
||
|
|
|
||
|
|
* The "range" of the pitch bend extends over the nearest two notes,
|
||
|
|
ie. when bent down to the minimum, notes sound two semitones lower
|
||
|
|
than normal, when bent up to maximum, notes sound two semitones
|
||
|
|
higher than normal.
|
||
|
|
|
||
|
|
* The full pitch table is in doom2.exe starting at 0x0008864c
|
||
|
|
|
||
|
|
* When bent up at the highest note, the MIDI code overflows the pitch
|
||
|
|
table slightly and uses the next value in memory (0x36c)
