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…

The KORG Collection is not just standalone software. As plug-ins. compatible with AU, VST, and the long-awaited AAX format, each synthesizer can be used in the various production environments found in Mac / Windows. Add flair to your music composition with a variety of timeless, legendary sounds. Now in Mac I only have the IAC in the device list. How can I create a Virtual Midi Device to show in the device list to choose to send midi to. Can I create a virtual device that uses the Apple DLS Synth? I don't really want have to put the Apple DLS Synth AU in a host with an IAC as input. Also where is the location of the Apple DLS Synth AU? Synthesizer free download - Zebra Software Synthesizer, Space Synthesizer, Vogue MK2 Synthesizer, and many more programs. ANTI TRANSPIRANT is a wonderful analogue sounding synth VST Instrument for.
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…
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 😀
I had some problems for saving preset in Ableton Live.
Synth1 can do an incredible variety of sounds.
The most versatile Synth in this list
2. OBXD AU / VST
The free Oberheim OB-X OB-Xa OB-8 emulation !
work without any problem in my AudioUnit / VST hosts on Mac.
3. Tyrell N6 AU / VST
DL here : http://www.amazona.de/amazona-de-freeware-synthesizer-tyrell-n6-v3/
U-He loves the Mac, don’t hesitate to have a look at the other freeware on the Website, all are working without problems in VST or AudioUnit format. I have also selected Triple Cheeze and Zebralette from the same developer. These plugins are good and full featured.
TyrellN6 plugin comes with a big amount of presets, and a deep variety of sounds. It’s powerful and easy to program. It’s rock solid stable and have a nice UI too!
4. FreeAlpha AU / VST
This freeware from LinPlug sounds very good, it has punch and is easy to tweak. It can do punchy bass, but also nice pads and clean leads. Despite its simple look, it’s powerful and funky!
5. Crystal AU / VST
The old Crystal Synth is still top, and one of the best synth for complex / evolving PADS, with its multipoint envelopes, and the complete modulation matrix.
One of the best virtual synth, for more than 10 years!
6. TAL NoiseMaker AU / VST
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.
7. Dexed FM VST
The famous free Yamaha DX7 emulation ! It’s VST only (no AU for the moment).
Use the cart / load / save button to browse or import presets.
It can read / write sysex files for and from the DX7.
Now all your FM needs are fullfilled: you can do pop ballad or Detroit techno, vive la FM !
8. MiniSpillage AU (Drum Synth)
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.
9. ComboF organ AU / VST
After all these synths, we now need an emulation of our prefered organ : the Farfisa combo organ!
ComboF gives you the sound of the Italian electric organ we all love. Available for Mac and windows, in AudioUnit and VST!
10. MrTramp 2 e-piano AU / VST
After the organ emulation, we need the electric piano! MrTramp 2 is the best (free or not) emulation of the Wurlitzer electric piano. It’s raining again ! Now you can sound like Supertramp ! Breakfast in America !! There are not so much controls but you don’t need more, and the sound is excellent.
11. Cheeze Machine AU
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.
12. TripleCheese AU / VST
Cheese again !
The U-He contribution to the first KVR Developer Challenge. It’s an original synth with unusual sound generation. Nice for plucked sounds. Works well on my Mac OS X Mountain Lion. Thanks to the comb filter, you can generate very original sounds.
13. Zr3 organ VST
We have ComboF for the Farfisa emulation, and for the Hammond B3 organ lovers, there’s Zr3.
It’s VST only and works nice in Ableton Live 9.
The only good free Hammond B3 emulation for Mac OS X.
14. TAL Elek7ro AU / VST
A perfect free synth for bass and perc sounds.
Don’t forget to check the other TAL plugins !
15. VST Speek AU / VST
Coming from here ! the funkiest text to speech in plugin format !
The best C64 Sam oldskool text to speech emulator, for all your techno voices.
Available in 32 & 64 bit, VST & AU
16. Zebralette AU / VST
Coming with the demo of Zebra, the famous synth by u-He, Zebralette is a nice synth, with unusual sound, and powerful possibilities and plenty of special waveforms to play with.
17. Model – E VST
The antic VST from Steinberg, now free, and now available in VST format for Mac OSX.
It has been surpassed in all domain by many other synth (freeware included). But it can be useful and you can get some nice sounds out of it if you tweak it with love.
18. VB-1 virtual bass VST
Another prehistoric virtual synth from Steinberg, this virtual bass plugin is free and available with Model E in the same package (see link above). Very simple sound, can be useful.
Freeware for Mac are rare so we take it!
19. MDA Piano ePiano DX10 & JX10 VST
These free VST work for Mac OS X, they don’t have UI, you’ll have to use the default interface supplied by your host.
– Piano & ePiano are sample based synth, the ePiano is very good, it’s a kind of Rhodes emulation.
– DX10 is a FM Synth, it has only two operators, but you can still get nice bell sounds out of it.
– JX10 is a very nice virtual analog synth, despite some bugs (the Windows version has the same), it can do some very nice leads.
20. 4Front R-Piano AU / VST
Another free electric piano emulation for your Mac!
It’s simple and has a nice clean sound. Perfect for deep house chords.

26. Bonus tracks ?
1) there’s also kickmaker, a free kick drum synthesizer in VST and AU format : http://teragonaudio.com/KickMaker.html
and C700, that can load sample in aiff and wav format :
2) I also tried other free VST plugins for MAC , but with no luck (no one working in any host on my Mac OS X Mountain Lion), i think these are too old plugins, or maybe ppc plugins (even if they were said to work on Mac OS X).
For example :
