Step-by-Step Guide

  1. Open your DAW's preferences and note which plugin formats it supports. This determines which installers to run.
  2. When running plugin installers, select only the formats your DAW uses. Installing unnecessary formats wastes disk space.
  3. Configure your DAW to scan the folders where your plugins are installed. Typical paths: VST2 in C:\Program Files\VSTPlugins, VST3 in C:\Program Files\Common Files\VST3.
  4. After installing new plugins, rescan the plugin list in your DAW. Restart the DAW if the plugins don't appear.
  5. Use a plugin manager or create subfolders by category (EQ, Compressor, Reverb) for easier browsing.
  6. Check for plugin updates regularly. Updates fix bugs, improve stability, and add features. Use a plugin manager like Patchwork or your own spreadsheets.

Frequently Asked Questions

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.
What is CLAP and should I use it?
CLAP is a modern plugin format with better multi-core support and flexible modulation. It's currently supported by Bitwig, REAPER, and Studio One. If your DAW supports CLAP and the plugin offers it, give it a try. That said, VST3 remains the safest choice for compatibility.
Can I convert between plugin formats?
No, you can't convert a plugin from one format to another. The developer has to compile the plugin for each format. If you need a specific format, contact the developer or use a plugin wrapper (with potential trade-offs in stability).
Do plugin formats affect sound quality?
No. The plugin format is just a wrapper. The audio-processing code inside is identical across formats. The VST3, AU, and AAX versions of the same plugin sound absolutely identical. The choice of format affects features and compatibility, not sound quality.
