So when this is lifted... 79 00:05:28,020 --> 00:05:29,880 Now you can see the channel is moving. 80 00:05:29,880 --> 00:05:35,360 As soon as I let go of the lever, that connection is broken. So now I can move this... 81 00:05:36,260 --> 00:05:37,640 But nothing is happening. 82 00:05:37,640 --> 00:05:39,640 Same here for the kick drum channel. 83 00:05:40,620 --> 00:05:43,580 Now it's not activated, as soon as I let go of this... 84 00:05:44,700 --> 00:05:46,400 The channel starts moving. 85 00:05:46,400 --> 00:05:53,580 I'm really proud of the fact that I've managed to have one lever control both this and this row. 86 00:05:54,880 --> 00:05:58,820 And I put so much effort into the muting system, 87 00:05:58,820 --> 00:06:02,440 just because it was the muting system that failed on the first machine. 88 00:06:02,440 --> 00:06:07,740 This system has actually worked since the very beginning.
