Nathan Blair Releases FREE Karp Synthesizer VST Plugin

Nathan Blair releases Karp Synthesizer, a freeware plucked string synthesizer in VST3 and AU plugin formats for digital audio workstations on Windows and macOS.

Karp Synthesizer uses a modified Karplus-Strong algorithm to synthesize plucked string sounds. It sports a streamlined user interface with straightforward controls and an animated background (using OpenGL).

Karp Synthesizer offers a very limited amount of tweakability with its two control knobs. The user can only adjust the decay time and the damping amount. Additional pitch-bend control is available with MPE.

On the other hand, the instrument sounds terrific out of the box, and it works great for synthesizing plucked sounds. The available controls can add subtle, yet interesting variations to the generated plucks, making Karp Synthesizer the perfect instrument to place after an arpeggiator or a step sequencer.

The GUI also features an image of a couple of dolphins jumping out of the water against a dreamy pink sky, and come on… who doesn’t like dolphins? So yes, the GUI easily gets a 10/10 rating in my book.

In all seriousness, Karp Synthesizer sounds surprisingly well for such a simple-looking plugin. You should definitely add it to your arsenal if you like experimenting with arpeggios and fast melodic sequences.

Karp Synthesizer is Nathan Blair’s first VST plugin release, but he has already developed several useful Max for Live devices. Some of those are also free; you find them all on the developer’s Gumroad page.

Karp Synthesizer is available in VST3 and AU plugin formats for 64-bit plugin hosts on Windows and macOS. Installation instructions are provided on the product page linked below.
