If you have a limited budget and want to get the tools you need for music production, here’s a list of free plugins that will work for Mac or PC.

Dynamics

This category includes compressors and limiters, used to shape the volume of tracks. A very essential music production tool for those that know how to use it.

I highly recommend this 10 hour video on compression - How to Use Compression. You can learn so much with just the first 3 hours of the video. I highly recommend watching just a bit at a time to take everything in.

Honestly you should be able to get by with the compressors included with your DAW, but these are free and might provide more options.

Equalizers

Filters

  • Filter Force Free - Provides 2 out of 21 filter types. Paid version is only $19
  • TAL Filter 2 - host synced filter module with different filter types, panorama and volume modulation possibilities. Can be used for tremolo or trance gate effects
  • Caelum Audio FluxMini 2 - filter with modulation options

Distortions / Saturators / Amp Simulators

Reverb / Echo / Delay

Chorus

  • TAL Chorus LX - vintage chorus effect that emulates the Juno 60 chorus

Tape Emulation

Tape emulation is very useful for obtaining a retro lo-fi feel with your recordings, adding noise and slight wavering to the audio.

Analyzers

Software Synthesizers

  • Classic Subtractive Synthesis - Good for beginners
    • Blamsoft
      • VK-1 Viking - Classic monophonic analog synthesizer. This is a great start for those wanting to learn classic subtractive synthesis such as that provided by the Minimoog
    • TAL
      • Tal Noisemaker - virtual analog synthesizer with a great sound and low CPU usage
    • Cherry Audio
  • Intermediate
  • Advanced
    • Vital
      • Vital - Wavetable / Additive synth
    • Surge
    • u-He
    • DSP56300 - Require firmware files to run, perhaps found in Internet Archive

      • OsTIrus - Access Virus TI/TI2/Snow emulation
      • Vavra - Waldorf MicroQ emulation
      • Xenia - Waldorf Microwave II/XT emulation

Modular Synths

I recommend that anyone wanting to understand synthesizers learn the basics of patching up a subtractive synthesizer, similar to the Minimoog, to understand how synthesizers are really wired internally. It will make it so that when you see a non-modular synthesizer, you’ll be able to guess how it works much easier instead of being mystified and confused.
