There's no glue, 00:04:42.880 --> 00:04:47.060 completely reversible if this would turn out to not work somehow. 00:04:47.060 --> 00:04:49.020 All channels are padded, 00:04:49.040 --> 00:04:53.680 and before testing, I thought that I take the opportunity to explain to you exactly 00:04:53.740 --> 00:04:57.600 how this muting system works, because once the marble divider is on here, 00:04:57.600 --> 00:05:00.440 you won't be able to see this like this ever again. 00:05:00.620 --> 00:05:06.340 Here we have six levers: vibraphone, kick drum, snare drum... 00:05:06.340 --> 00:05:10.120 hihat, cymbal, bass guitar. 00:05:10.120 --> 00:05:18.660 The movement is transmitted from my lever here, both to this row here and onto this row up here. 00:05:18.660 --> 00:05:24.520 So when the vibraphone is activated when it's playing, we have a physical connection... 00:05:24.520 --> 00:05:27.980 going on over here. So when this is lifted... 00:05:28.020 --> 00:05:29.880 Now you can see the channel is moving. 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... 00:05:36.260 --> 00:05:37.640 But nothing is happening. 00:05:37.640 --> 00:05:39.640 Same here for the kick drum channel. 00:05:40.620 --> 00:05:43.580 Now it's not activated, as soon as I let go of this... 00:05:44.700 --> 00:05:46.400 The channel starts moving. 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. 00:05:54.880 --> 00:05:58.820 And I put so much effort into the muting system, 00:05:58.820 --> 00:06:02.440 just because it was the muting system that failed on the first machine. 00:06:02.440 --> 00:06:07.740 This system has actually worked since the very beginning. I never had to change... 00:06:07.740 --> 00:06:10.140 any of the designs for this. 00:06:10.140 --> 00:06:13.260 So, all the channels are now in a muted position, 00:06:13.260 --> 00:06:19.620 which means we will only see the registrators move, but none of the channels are activated. 00:06:19.620 --> 00:06:21.300 Look in the back: 00:06:30.720 --> 00:06:34.420 So, only the registrations were moving — nothing else. 00:06:34.420 --> 00:06:38.820 Let's activate the big vibraphone, and this channel. 00:06:39.040 --> 00:06:40.700 Uh... this channel. 00:06:50.800 --> 00:06:52.800 Let's do the opposite! 00:07:04.500 --> 00:07:10.680 Here you can see the hooks that is the breaking and activation of the mechanical connection. 00:07:11.180 --> 00:07:11.940 [metallic slam] 00:07:11.940 --> 00:07:18.800 So that's what happens when we mute an instrument group, and that's what happens when we activate it. 00:07:19.420 --> 00:07:24.320 You can see if a programming pin activated this, it will pull the channel. 00:07:26.120 --> 00:07:29.420 And when it goes down, it will not pull the channel. 00:07:30.240 --> 00:07:34.460 This system is also designed to handle the following edge case: 00:07:34.460 --> 00:07:37.680 Let's say the instrument loop is muted [metallic slam] like that. 00:07:38.580 --> 00:07:43.140 But this is still moving due to the registrators being hit by the programming pins. 00:07:43.520 --> 00:07:49.400 So imagine a pin is just hitting this, and at the same time I'm unmuting this instrument group. 00:07:50.280 --> 00:07:54.020 Then we have this situation, but when the pin let's go 00:07:54.740 --> 00:07:56.740 Everything sort out itself. 00:07:56.840 --> 00:08:05.360 That's why we have these diagonals on these hooks. It's basically only for that specific edge case. 00:08:07.760 --> 00:08:11.160 Let's try to cut some registrators, shall we? 00:08:11.160 --> 00:08:15.900 I'm super nervous to mess up this expensive PUM Delrin material. 00:08:15.920 --> 00:08:19.460 [♪ Wintergatan - Helping Out In Eb Major (Unreleased) ♪ ] 00:08:19.460 --> 00:08:24.760 [CNC machine whirrs] 00:08:27.760 --> 00:08:31.120 [muffled speaking] 00:08:42.040 --> 00:08:43.220 [Delrin blocks fall onto wood] 00:08:52.300 --> 00:08:53.740 [CNC machine whirrs] 00:08:58.620 --> 00:09:01.560 [CNC machine whirrs] 00:09:16.020 --> 00:09:22.280 So Toby came in and saw me cutting and asked: "Do you have a fence?" and I was like: "Yeah!" 00:09:22.600 --> 00:09:26.680 And then he said: "I think you're gonna get some safety comments if you don't use a fence." 00:09:26.680 --> 00:09:31.920 And I'm gonna be totally honest, I never thought about using the [blows away dust] 00:09:31.920 --> 00:09:34.220 fence for safety like this. 00:09:34.220 --> 00:09:40.180 Yeah, being the stupidest person in the room is the best situation you can find yourself in, 00:09:40.180 --> 00:09:42.160 'cause that's where you're learning. 00:09:42.160 --> 00:09:47.460 [♪ Wintergatan - Helping Out In Eb Major (Unreleased) ♪] 00:09:51.080 --> 00:09:57.420 [Martin humming a melody] [♪ PewDiePie - B*tch Lasagna ♪] 00:09:58.880 --> 00:10:04.960 I have all my registrators, and I have all my fingers.
