When playing Necros' "Ascent Of The Cloud Eagle" using an AWE32
with xmp I noticed that awedrv 0.4.2c does not play notes higher
than C7. The problem happens in the following track (order 29,
pattern 47, channel 5, rows 0x16 to 0x1d).
16 |G-7 07 .. 000 000 |
17 |A-7 07 .. 000 000 |
18 |F#7 07 .. 000 000 |
19 |... .. .. 000 000 |
1A |D-7 07 .. 000 000 |
1B |E-7 07 .. 000 000 |
1C |F#7 07 .. 000 000 |
1D |... .. .. 000 000 |
1F |G-7 07 .. 000 000 |
20 |G-6 07 .. 000 000 |
21 |C-7 07 .. 000 000 |
22 |B-6 07 .. 303 000 |
23 |C-7 07 .. 300 000 |
24 |... .. .. 300 000 |
Awedrv sets rec->high to 'freq_to_note (patch.high_note) / 100'
clipping to an upper value of 12799:
awedrv/awe_wave.c:
3345 rec->root = note / 100;
3346 rec->tune = -(note % 100);
3347 rec->low = freq_to_note(patch.low_note) / 100;
3348 rec->high = freq_to_note(patch.high_note) / 100;
899 /* convert frequency mHz to abstract cents (= midi key * 100) */
900 static int
901 freq_to_note(int mHz)
902 {
(...)
915 freq = mHz;
916 note = 0;
917 for (base = 8176 * 2; freq >= base; base *= 2) {
918 note += 12;
919 if (note >= 128) /* over maximum */
920 return 12799;
xmp/src/player/driver.c:
299 patch->base_note = C4_FREQ;
300 patch->base_freq = basefreq;
301 patch->high_note = 0x7fffffff;
302 patch->low_note = 0;
The range in note numbers for octave 7 is 84 to 95, and awedrv's
limit should be 127. The module is correctly played using a GUS
or the software mixer.
