Free String Machine VST/AU Plugins


In this edition of bpb Freeware Studio, we’ll be covering the best free string machine VST/AU plugins for Windows and Mac OS.

String machines (otherwise known as string ensemble synthesizers) were among the most popular instruments back in the 70s – two of the most notable examples being the Arp Solina and Crumar Performer. The simple synthesizers were quite limited in terms of sonic flexibility, but musicians often used outboard effects such as phasers and chorus pedals to effectively expand their sound (which resulted in some fairly epic sounds in the right hands).

The plugin which inspired me to make this list is The deputy Mark II by Full Bucket Music. It was released quite recently, but quickly became my favorite freeware string machine VST plugin, due to its great sound and brilliant control layout.

eSLine is a simple and effective emulation of the Arp Solina String Ensemble. Much like its real life counterpart, eSLine has separate violin, viola, trumpet, horn, cello and contrabass sections which can be mixed independently.

Cheeze Machine is the only plugin from the list which is also available for Mac users. It is a very capable virtual string machine, featuring a chorus ensemble emulator, a 6-stage phaser, and a handy reverb unit.

  1. Nice list, but I wanna recommend also the String Synthesizer from Algo Music, which sounds very phat. Another good one is StringZ II from krakli software. Now let’s ask Mozart what string synthesizer he would prefer… :-)

      • i agree string z ii is amazing! thanx for the list as well, will be checking out this synths since iv never heard of most of them!

        thanks for the suggestion! i agree that StringZ sounds very nice, but it’s (unless i’m mistaken) a physical modeling synth and not an emulation of those old school string machines. i might make a separate bpb Freeware Studio for such synths in the future, though! there are quite a few interesting ones around.

  2. In addition to the above (excellent!) string synths you mentioned, I would like to suggest one of my own creations. Stringz N’ Things is a free simulation of the Paia Stringz N’ Thingz, which as far as I can tell has never been emulated/sampled before. I used the Paia service manual’s settings to get the string/piano sounds as close as I could to the real thing. It’s a synthedit (win only) synth though. You can check for sound examples and a download link. Thanks and enjoy!

  3. Cheeze Machine has been discontinued by Big Tick Audio (as has all their freeware). It has however been reissued by 2gether Audio and is available from They’ve given it a new coat of paint and dragged it into the 21st century (it’s now 64-bit).

    2gether have also modernised the Ticky Clav clavinet emulator, but alas Angelina, EP-Station, and Rainbow have not been reissued.
