StringLab is a physical string modeling synthesizer based on Karplus-Strong theory. It is capable of reproducing the sounds of many different types of instruments, but is especially useful in the reproduction of hammered or plucked strings and other types of percussive instruments.

It works by passing carefully crafted waveforms and short bursts of white noise through a series of tuned delay lines. The delay lines have an internal feedback loop with a series of filters to mimic the natural decay of harmonics found in a real instrument. StringLab allows you to discover the character of real-world accoustics, exploring the physics of how materials interact. Many new and original textures are born out of experimenting with the settings, so don't be afraid to experiment and create your own unique and dynamic instruments.

Best randomizer ever ! And more!

This is seriously the best randomizer I have yet to use, hands down. Tied with physical modeling it’s out of this world. This could have been such a higher cost and is an amazing new and innovative tool for sound design. I have and love Pianoteq so I absolutely love the chance to sound design to this degree with so many types of instruments. But this randomizer , I have just made and saved so many new presets. Also fun to randomizer than tweak , just for a fun little activity. Thanks for creating!

Developer Response ,

Thanks for supporting the product and being so enthusiastic about the randomizer.

Great app but it needs CC mapping

Really nice app but I am surprised you don’t have any provision to map CC controls with it. I play a windsynth controller and this is a must need for the synths I use. I am aware I can probably map parameters in AUM and use Loopback to get the audio into Logic but that introduces more latency. Hope you can add CC mapping to this app and Copperhead (also a great synth)

Developer Response ,

Unlike typical synths based on additive synthesis, this app uses Karplus Strong which is based on delay lines and feedback loops. This can soon get out of control I give external access to some controls so I have imposed limits in the initial release. I am introducing some CC control into the next version of the app, but only those parameters that are safe to do so.
