This post is for the Mac users.
When it comes to Mac OS X, the number of freeware plugins is very low, compared to the Windows world.
The popular “Save as VST” softwares (Synthedit and Synthmaker) are Windows only.
The “upgrade” politic of Apple is a sort of nightmare for developers (and sometimes users!), so many old free plugins don’t work anymore…

I have searched for free MAC plugins over the web and then tested !
– only free synth (not effects), in VST and or AudioUnit (AU) format
– the OS used is Mac OS X 10.8 (Mountain Lion)
– i tested the plugins in Ableton Live 9 / Renoise / some free VST & AudioUnit host softwares (Pedalboard, the JUCE open source plugin host, VSTLord, AULab, Ugly VSTi Interface…)

It’s a selection with free virtual analog synths, organ emulations, epiano emulations, drum synth, bass synth, FM synth, emulation of Oberheim / NordLead / DX 7 synth, chip synth, guitar emulation…

Garageband – Daws For Mac. Pro Tools First. Pro Tools First DAW for Mac comes with UVI Workstation 3 player and Xpand! 2 virtual instruments which lets you connect with scores of loops, sounds, beats, and power chords, etc. The free version of it offers to record two tracks simultaneously and play 16 tracks in the at the once, it also has. These are the best FREE realistic instrument VST/AU plugins for Windows & Mac! Some of these virtual instruments actually come as AU so they can work in Gara. Surge By Vember Audio. The award-winning Surge is incredibly popular, and some even call it the best free VST synth available. This open-source hybrid subtractive digital synthesizer comes with 2,116 patches (with two scenes) and 614 wavetables, which is quite stunning already. It has a quick-category patch browser too. The first one I want to mention is Spitfire LABS, a great resource to get free orchestral. In this list we are gonna go over the best free VST instruments with those for a budget. All these have the best price which is free. First we need to clarify a difference to avoid a confusion about this list. VST Instruments: This is all the virtual synthesizers or instruments samples that produces audio. Examples can be FM synthesis, pianos.

and here a list of 25 free synth plugins for Mac OS X :

1. Synth1 AU/ VST

The must-have free synth plugin is available for Mac since one or two years, it is in beta state, it still have some minor bugs with the UI, but it’s usable and you can benefit from the incredible amount of presets created for Synth1, including these 😀

Like U-He, TAL has many freebees for Mac OS X.
I have selected Noize M4k3r and Elek7tro but you also have other interesting plugins.
The “Noise Maker” plugin has two osc + sub, a good filter and the famous Chorus “a la Roland”, so you have all you need for your fat bass/lead. Certainly more agressive than Crystal, it completes well the sonic arsenal.

It can read / write sysex files for and from the DX7.

MiniSpillage AU

Now that we have the FM synth, the Pad synth, the Bass synth and Lead capable synths, we need a DRUM synth. The Minispillage plugin has three dedicated algo for bass drum, wood drum and hihat.
I tend to prefer “Drumatic” but Drumatic is Windows only.

A dedicated string synth plugin for Mac ! The Cheeze machine from Big Tick is a kind of Arp Solina emulation. It has this phaser / chorus creamy sound.
it’s AU only and should work with your favorite Mac host software.
