00:00:00,000 --> 00:00:06,000
Welcome to the MiniTamTam demo tutorial.

2
00:00:06,000 --> 00:00:11,000
MiniTamTam is an application that will be included on the OLPC XO computer.

3
00:00:11,000 --> 00:00:17,000
It has three applications, MiniTamTam, the TamTam Editor, and SynthLab,

4
00:00:17,000 --> 00:00:21,000
that will allow children to play music on the XO computer.

5
00:00:21,000 --> 00:00:23,000
So I will first show you MiniTamTam.

6
00:00:23,000 --> 00:00:31,000
So to launch MiniTamTam, you move your cursor to the frame of the screen,

7
00:00:31,000 --> 00:00:39,000
and you launch MiniTamTam by clicking on the little drum icon here.

8
00:00:39,000 --> 00:00:43,000
So once you are in MiniTamTam, you will see the interface,

9
00:00:43,000 --> 00:00:46,000
which consists of different instrument icons here,

10
00:00:46,000 --> 00:00:52,000
and you have the right part, which controls the different drum and beats,

11
00:00:52,000 --> 00:00:54,000
and then you have sliders at the bottom.

12
00:00:54,000 --> 00:00:57,000
So I will start with the icons here.

13
00:00:57,000 --> 00:01:01,000
So each icon represents a sound, and when you click on it, you can hear it.

14
00:01:01,000 --> 00:01:07,000
So for instance, the piano, saxophone, bottle here.

15
00:01:07,000 --> 00:01:12,000
You can also select different sounds by moving the arrow keys on the keyboard.

16
00:01:12,000 --> 00:01:18,000
So you can cycle through sounds, and this is quite handy when you want to quickly preview what sound you want.

17
00:01:18,000 --> 00:01:21,000
This is a little didgeridoo here.

18
00:01:22,000 --> 00:01:28,000
So you can actually play the sounds, the different instruments, using the OLPC XO keyboard.

19
00:01:28,000 --> 00:01:34,000
So if I start here, you see this is a normal major scale,

20
00:01:34,000 --> 00:01:37,000
and the keyboard is laid out like a piano.

21
00:01:37,000 --> 00:01:44,000
So actually it starts on the Z key for the lower octave,

22
00:01:44,000 --> 00:01:46,000
and stops on the comma here,

23
00:01:46,000 --> 00:01:51,000
and you have the black keys of the piano on the upper row.

24
00:01:51,000 --> 00:01:55,000
So starting at S, you have C sharp.

25
00:01:58,000 --> 00:02:00,000
So you can easily play like a normal piano.

26
00:02:00,000 --> 00:02:03,000
So I will just choose another sound, which will be easier to...

27
00:02:03,000 --> 00:02:09,000
So I can do a major chord, I can do a minor chord, like a normal piano,

28
00:02:09,000 --> 00:02:13,000
and the second octave starts on the Q key.

29
00:02:16,000 --> 00:02:23,000
And once again, you can do the black keys by pressing 2 and 3, then 5, 6 and 7.

30
00:02:23,000 --> 00:02:27,000
So now we will look at the drum sections.

31
00:02:27,000 --> 00:02:32,000
So basically, to start a drum, the drums are generated by an algorithm.

32
00:02:32,000 --> 00:02:35,000
So each time you generate a new drum, the beat will be slightly different,

33
00:02:35,000 --> 00:02:38,000
and you have three parameters you can use to control the drum.

34
00:02:38,000 --> 00:02:40,000
You have the complexity of the beat,

35
00:02:40,000 --> 00:02:45,000
you have the length of the beat, which means the length of the actual loop,

36
00:02:45,000 --> 00:02:46,000
and you have tempo.

37
00:02:46,000 --> 00:02:49,000
And I will start a beat to show you.

38
00:02:49,000 --> 00:02:54,000
So you click the little dice there, which will start a beat.

39
00:02:54,000 --> 00:02:56,000
You can then choose different drum kits.

40
00:02:56,000 --> 00:02:58,000
You can choose the Arabic kit here.

41
00:03:01,000 --> 00:03:03,000
You can choose the African kit.

42
00:03:05,000 --> 00:03:08,000
And now if we want to change the parameters, we can change them in real time.

43
00:03:08,000 --> 00:03:11,000
So I can select here the complexity and erase it.

44
00:03:12,000 --> 00:03:14,000
And as you see, the beat is more complex now.

45
00:03:14,000 --> 00:03:17,000
You can also change the length to a longer value.

46
00:03:21,000 --> 00:03:23,000
So now the loop is longer.

47
00:03:25,000 --> 00:03:27,000
Then the tempo, we can slow it down.

48
00:03:33,000 --> 00:03:35,000
Put it faster.

49
00:03:36,000 --> 00:03:38,000
Put it faster.

50
00:03:40,000 --> 00:03:43,000
And each time I click on the dice, I will generate a new beat

51
00:03:44,000 --> 00:03:46,000
using the parameters of the sliders.

52
00:03:48,000 --> 00:03:51,000
Then we have the stop and play button here,

53
00:03:51,000 --> 00:03:54,000
which you can use to stop or play your beat.

54
00:03:56,000 --> 00:04:00,000
And when you have a beat running, I will just put it a little slower.

55
00:04:05,000 --> 00:04:08,000
You can play the keyboard and the instruments.

56
00:04:18,000 --> 00:04:20,000
Now I will just stop the beat here.

57
00:04:24,000 --> 00:04:26,000
So there are two sliders at the bottom of the screen.

58
00:04:26,000 --> 00:04:28,000
There is the volume slider here.

59
00:04:28,000 --> 00:04:32,000
So if I put it down, you will see the sound is lower and I can erase it.

60
00:04:32,000 --> 00:04:34,000
It's a normal volume slider.

61
00:04:36,000 --> 00:04:38,000
Then you have the reverb slider.

62
00:04:38,000 --> 00:04:41,000
The reverb will add some reverb to the sound.

63
00:04:41,000 --> 00:04:46,000
So if I put it up, you can hear a little echoing there.

64
00:04:48,000 --> 00:04:53,000
And now if I start a beat, there will be some echo or reverb on the beat also.

65
00:04:56,000 --> 00:04:58,000
You can choose this kit here.

66
00:05:02,000 --> 00:05:03,000
And start it again.

67
00:05:03,000 --> 00:05:04,000
Actually, I need to generate.

68
00:05:05,000 --> 00:05:06,000
Ah, there we go.

69
00:05:08,000 --> 00:05:10,000
So now we have a lot of reverb on the drum.

70
00:05:12,000 --> 00:05:14,000
Now I will explain that lower row here,

71
00:05:14,000 --> 00:05:18,000
which you can see four little microphones here.

72
00:05:19,000 --> 00:05:21,000
And above the microphones, you have little record buttons.

73
00:05:21,000 --> 00:05:25,000
So this means that you have four slots where you can record your own sound.

74
00:05:25,000 --> 00:05:28,000
And to do so, you just click the record button here.

75
00:05:33,000 --> 00:05:35,000
And then you can play it back on the keyboard.

76
00:05:35,000 --> 00:05:37,000
So now you see that I have some reverb.

77
00:05:37,000 --> 00:05:39,000
I will just remove a bit of reverb there.

78
00:05:41,000 --> 00:05:43,000
And then you can play it like any other instrument.

79
00:05:49,000 --> 00:05:50,000
There you go.

80
00:05:50,000 --> 00:05:54,000
So now you can record up to four sounds using the microphone slots.

81
00:05:54,000 --> 00:05:57,000
And then we have the SynthLab buttons here.

82
00:05:57,000 --> 00:06:00,000
SynthLab is another application within TamTam

83
00:06:00,000 --> 00:06:03,000
which allows you to create your own sounds using synthesis.

84
00:06:03,000 --> 00:06:07,000
So to open SynthLab, you can just click the little record button here,

85
00:06:07,000 --> 00:06:10,000
which will open a preset in SynthLab.

86
00:06:10,000 --> 00:06:12,000
And I will explain this in another video.

87
00:06:12,000 --> 00:06:15,000
But for now, we can just hear what this preset sounds like.

88
00:06:18,000 --> 00:06:19,000
There we go.

89
00:06:19,000 --> 00:06:21,000
It's a little long, so I'm just going to adjust the duration here

90
00:06:21,000 --> 00:06:24,000
because I want to show you how it integrates with Mini TamTam.

91
00:06:26,000 --> 00:06:29,000
So when you're happy with the sound there, you just click record here.

92
00:06:29,000 --> 00:06:30,000
Click your sound.

93
00:06:30,000 --> 00:06:31,000
Play it on the keyboard.

94
00:06:31,000 --> 00:06:33,000
You can play multiple notes also.

95
00:06:33,000 --> 00:06:34,000
Close it.

96
00:06:34,000 --> 00:06:38,000
And then the sound will be in Mini TamTam.

97
00:06:38,000 --> 00:06:42,000
And you can record up to four sounds also using this technique.

98
00:06:43,000 --> 00:06:46,000
So this is pretty much the end of the Mini TamTam tour.

99
00:06:46,000 --> 00:06:49,000
We will show you a SynthLab video pretty soon.

100
00:06:49,000 --> 00:06:50,000
I hope you enjoyed it.

101
00:06:50,000 --> 00:06:51,000
Thank you.
