音响设计教程：创建一个TB - 303补丁在Spectrasonics Trilian

Toby Pitman on Jun 29, 2011 in Audio Software 3 comments

I very much doubt that when Tadao Kikumoto designed Roland's TB-303 in the early 80s, he knew that he would be starting a cultural revolution! On its release in 1981...  

我很怀疑，当忠雄Kikumoto在80年代初设计Roland的TB - 303，他知道，他将开始一场文化革命！在它的发行在1981年的产品，作为一个简单的低音歌手和词曲创作者的伴奏下框的，

然后在1987年，总部位于芝加哥的装备称为Phuture公布所谓的酸性轨道的acid house出生轨道。 TB - 303定义歌曲的声音！ Squelchy，谐振，扭曲和重复。

从那时起就出现了数万数以千计的记录，从流行嘻哈，电子摇滚到环境。而且它依然强劲！


在Trilian一个模拟TB - 303

当然也有一些优秀的303个可用专用的软件和硬件仿真（如果你不想花原始2,000美元，与日本的手册，!!!).

不过，这是很容易敲Spectrasonics“重地低音合成一个 Trilian，轻松了许多方案。听起来不错，太！让我们做吧！


第1步 - 波形

打开Trilian并选择“编辑”窗口。点击面板打开浏览器的中心Soundsource形象。


Navigate down the Source list to Roland TB-303 and select the waveform called TB-303 Sawtooth.

Half the battle is already won as Spectrasonics has lovingly sampled the waveforms from the original model, which does have quite a distinctive sound.

第2步 - 信封

Go back to the Edit window and set the Amp and Filter envelopes like so:


On both envelopes, turn down the Velocity ('VELO') knob to 0%. Done!

第3步 - 过滤

Turn the Filter section On and load in the 'LPF Juicy 24db' Lowpass from the drop down menu. Set the ENV amount to 0%.

第4步 - 语音控制

Now it’s time to set up the Voice Controls for the sound. These are on the right-hand side of the Edit window. Set them up like this:

The sound is monophonic so I’ve enabled Solo (in Legato mode, the tiny 'L' to the left of the Solo button) with 'Voices' set to 1 (to be on the safe side!). The 'Oct' is set to 0, and the 'Gain' to -6 db.

The Glide is on (again, in Legato mode) for Layer A with a time of 9ms. I found this to be the optimum time setting when comparing against other 303 clones. 

Solo and Glide are very important as they affect how the Note triggering, Envelopes and Portamento effect work on overlapping notes. 

第5步 - 编程序列

How you program your sequence will affect how the 303 sound will work. The TB-303 has two kinds or notes, short and tied.

Short notes I found have a length of about 2/3 of a 16th-note. The gap between them, apart from sounding right ensures that the sample is re-triggered, as well as the Filter envelope.

Any longer notes you program should have this gap at the end, too. Long notes on a 303 are made by putting two notes of the same value one after the other and enabling Glide to the first note. This ties them together to make one note. 


On the 303 you will only hear the Portamento Glide effect if the two ‘tied’ notes have different pitches. In a sequencer this is done by overlapping notes. You can hear this in the example below.



The time we set for the Glide (9ms) is constant so the farther away from each other the notes are, the more extreme the effect.

These overlapping notes also serve to prevent the sample re-triggering from the start (Solo mode) and also stop the Filter envelope from re-triggering. The Glide and Filter envelope are two trademark sounds of the 303.

Here’s a sequence I’ve put together. It has short, long and overlapping notes. Here it is with the Filter set to 1370 kHz. You can copy it or make your own to test the sound.



Not bad, eh?

第6步 - 主控制分配参数

Before we start to tweak this sound I’m going to assign the parameters I need for the Patch to do its thing to the Macros in the Main Controls page. This just makes it easier to reuse the Patch later and looks cool as well!

If you switch to Main you’ll see the default Controls mapping. These are dead easy to change. First, I’m going to map the Filter's Cutoff.

Before you assign a new parameter to the control it’s a good idea to clear it as it will already have parameters assigned to it. If you don't, your new parameter will be added to the list which could cause some problems later. 

Control-Click on the Cutoff knob and choose 'Clear all parameter assignments for this control'.

Now Control-Click again and choose 'Assign this control to the next  touched audio control'. Go to the Edit page and click Cutoff in the Filter section.

Rename the new assignment CUTOFF.

Repeat these steps with the Filter Resonance (RESONANCE), Envelope Depth (ENV MOD) and Filter Decay (ENV DECAY) parameters.

Now I’m going to assign these Controls to a Group. I do this by clicking and dragging left on the the far right corner of the separator bars. A new Group is created called 'Group 2'. We’ll use it later.

You can now assign these hardware MIDI faders by Control-Clicking on each knob and choosing  'MIDI CC Learn'. You could also use your host's automation assignments for these, too. In Logic, for example, it's the Controller Assignments window.

Now I’m all hooked up, and I'm ready to record some tweaking. Here’s a quick example. I’m just playing with CUTOFF, RESONANCE, ENV MOD and ENV DECAY parameters.




That’s about it for the basic setup. Save out your Patch. Don’t forget you can always use the TB-303 Square waveform by simply switching to it in the Soundsource window.

第7步 - 添加效果

You can go a step further and add Distortion and Delay to make a more aggressive 303 Patch if you like. Here’s a setup I made for mine:

And here's how I’ve assigned the parameters to the Main Controls:

The result is pretty hardcore!


So that’s it! A TB-303 in Trilian. The only thing you need now is a large field to stand in and some glow sticks!

Hello !!! I know this is from 2011 but ... can't figure out how to do this :(
I've done 20 times exactly what its said on this tutorial but I've absolutely not the same sound at the end

Maybe someone can help me? does there is some stuff not explained here? or maybe with an update this tutorial is not functional anymore?

thanks if someone see this :)
