Ticks are imaginary units of time that determine note length for MML. They're quite useful for compression or for finding notes with just the right length. They can be based off the number of ticks in a whole note. The other values can be found simply by dividing and rounding or something like that.
This is a chart of note lengths and ticks based off 3ML2 (and 3ML too, I guess.)
Code:
note length = ticks
1 = 384 1. = 576
2 = 192 2. = 288
3 = 128 3. = 192
4 = 96 4. = 144
5 = 76 5. = 114
6 = 64 6. = 96
7 = 54 7. = 81
8 = 48 8. = 72
9 = 42 9. = 63
10 = 38 10. = 57
11 = 34 11. = 51
12 = 32 12. = 48
13 = 29 13. = 43
14 = 27 14. = 40
15 = 25 15. = 37
16 = 24 16. = 36
17 = 22 17. = 33
18 = 21 18. = 31
19 = 20 19. = 30
20 = 19 20. = 28
21 = 18 21. = 27
22 = 17 22. = 25
23 = 16 23. = 24
24 = 16 24. = 24
25 = 15 25. = 22
26 = 14 26. = 21
27 = 14 27. = 21
28 = 13 28. = 19
29 = 13 29. = 19
30 = 12 30. = 18
31 = 12 31. = 18
32 = 12 32. = 18
33 = 11 33. = 16
34 = 11 34. = 16
35 = 10 35. = 15
36 = 10 36. = 15
37 = 10 37. = 15
38 = 10 38. = 15
39 = 9 39. = 13
40 = 9 40. = 13
41 = 9 41. = 13
42 = 9 42. = 13
43 = 8 43. = 12
44 = 8 44. = 12
45 = 8 45. = 12
46 = 8 46. = 12
47 = 8 47. = 12
48 = 8 48. = 12
49 = 7 49. = 10
50 = 7 50. = 10
51 = 7 51. = 10
52 = 7 52. = 10
53 = 7 53. = 10
54 = 7 54. = 10
55 = 6 55. = 9
56 = 6 56. = 9
57 = 6 57. = 9
58 = 6 58. = 9
59 = 6 59. = 9
60 = 6 60. = 9
61 = 6 61. = 9
62 = 6 62. = 9
63 = 6 63. = 9
64 = 6 64. = 9
65 = 0
I was wondering if these are the same values used for the game, as I used to refer to a chart that had the whole note's value as 192 ticks (resulting in different values.) I know that being 1 tick off makes very little difference, but the note lengths can add up and sound poorly in the right situation.
