Step-by-Step Guide

  1. Open your DAW preferences and note which plugin formats it supports. This determines which installers to run.
  2. 執行外掛安裝檔時，只選擇你的 DAW 實際使用的格式。安裝不必要的格式只會浪費硬碟空間。
  3. Configure your DAW to scan the folders where plugins are installed. Common paths: VST2 in C:\Program Files\VSTPlugins, VST3 in C:\Program Files\Common Files\VST3.
  4. After installing new plugins, rescan your plugin list in your DAW. Restart the DAW if plugins don't appear.
  5. 使用外掛管理器，或按類別（EQ、壓縮器、混響）建立子資料夾，便於瀏覽查詢。
  6. Regularly check for plugin updates. Updates fix bugs, improve stability, and add features. Use a plugin manager like Patchwork or custom spreadsheets.

常見 問題

Can I use VST plugins in Logic Pro?
No. Logic Pro supports only AU plugins. If a plugin doesn't offer an AU version, you can't use it in Logic Pro. There are some wrappers (like Blue Cat's PatchWork), but native AU is always more stable.
What's the difference between VST and VST3?
VST3 offers sample-accurate automation, dynamic I/O, better CPU efficiency, and dedicated sidechain inputs. VST2 lacks these features. Always choose VST3 when it's available, but keep VST2 for older plugins that don't have VST3 versions.
Why aren't my plugins showing up in my DAW?
Common causes: the wrong format is installed (for example, VST2 in a VST3-only DAW), an incorrect plugin path in the DAW's settings, a 32-bit plugin in a 64-bit DAW, or a plugin that requires authorization before use. Check all of these settings and rescan.
什麼是 CLAP，我該使用它嗎？
CLAP 是一種現代外掛格式，擁有更好的多核支援和靈活的調製功能。目前 Bitwig、REAPER 和 Studio One 都支援它。如果你的 DAW 支援 CLAP 而且外掛也提供該格式，不妨試一試。話雖如此，從相容性來看，VST3 仍是最穩妥的選擇。
我能在不同外掛格式之間轉換嗎？
不能，你無法把一個外掛從一種格式轉換成另一種格式。開發者必須為每種格式分別編譯外掛。如果你需要某種特定格式，請聯系開發者，或者使用外掛封裝器（wrapper，但可能在穩定性上有所取捨）。
外掛格式會影響音質嗎？
不會。外掛格式只是一個殼層。其內部的音訊處理程式碼在各格式之間是完全相同的。同一個外掛的 VST3、AU 和 AAX 版本聽起來完全一致。格式的選擇影響的是功能和相容性，而非音質。
