Logic Proの中のマルチバンドチューブコンプレッサーを作成する方法

While Logic Pro 9 comes bundled with a very capable Multiband Compressor it lacks the circuit types found in the standard compressor. Mike Watkinson wires up a solution using Aux channels.  

Logic Proのhasn'tは、専用のマルチバンドチューブコンプレッサープラグインを得た。同じコンプレッサーの回路タイプのオプションは、ロジックスで発見するいくつかの憶測があった標準的なコンプレッサープラグインがバージョン9でMultiPressorに追加された、しかしそれがためにではなかったことでしょう。たぶん、Logic ProのXで?それまでは、補助チャネルを使用して独自に構築することができます。多分、そのシグナルプロセッサを作成しないように最も簡単な方法が、あなたはそれが実際に何をしているかを理解する可能性が高いかもしれません!



  1. Add three stereo auxiliary channels by clicking the ‘+’ button on the far left of the mixer (choose the first available bus as the input, and tick the ‘Ascending’ box)
  2. Set up a send to each auxiliary channel from the channel that contains the file you are mastering
  3. Set send levels to 0dB by Option-Clicking on the send level
  4. Add a low-pass filter to the first Aux channel (the low end signal), and a hi-pass filter to the third Aux channel (the top end signal) and set the cutoff points to taste
  5. Add a High Cut and a Low Cut filter to the second Aux channel (the mid-range); this is in place of a bandpass filter which Logic does not provide. Set the cutoff points to coincide with those in the lo and hi-pass filters
  6. Add Logic’s Compressor plug-in to each auxiliary channel (after the filter)
  7. Set each compressor to the circuit type of your choice (see below)


MultiBand tube compression with three bands



MultiBand tube compression using Multipressors as filters



  • Platinum: Emagic’s own compression algorithm
  • Class A_R: Neve 2264/33609; the R is for Rupert. This would be vacuum tube style compression
  • Class A_U: Vari-Mu e.g. Fairchild 670/Manley. Again a vacuum tube emulation, but designed to be more transparent than the R.
  • VCA: DBX 160/SSL G-Master buss compressor
  • FET: Urei 1176 or similar
  • Opto: Teletronix LA2A or similar

Excellent tutorial. I like the idea of using the Multipressor as a frequency splitter. This can come in handy as well to split the frequencies up and apply different effects other than compressors on the different frequency bands for.
Yes - that's a great idea. I particularly like the way you can easily decide to split frequncies into 2,3 or 4 bands!
Thanks for the comments

Does anyone know - Do I need to do this tube compression if sound was already coloured by compressor while it was at mix? Because to colour 2 times the same sound I think isn't a good idea...
Well...the amount of colour you decide to add is completely up to you and what your ears decide. Sometimes a track will need a lot of colour - sparse hip hop for example benefits from extra colour and crunch; busy mixes with lots of distorted sounds (guitars, vocals etc.) might suffer from too much colour. What's important is to have a range of tools available to you so you can tailor your production to the needs of your ears (and your clients of course!)...
