Kapling is a simple little standalone physical modeling synthesizer application for Mac OS X built with Max/MSP 5
It is based on the Karplus-Strong algorithm. Kapling uses this method to attempt the emulation of resonant bodies, like a string being plucked, or melodic percussion instrument being struck.
Eight independent voices are triggered by a 32-step sequencer, with a variety of parameters set up to help you sculpt new timbres in realtime. Kapling also features a tempo-synced stereo delay and recording to disk.
In simpler terms, Kapling can help you make twangy, boingy, klonky tones.
You can preview Kapling below. You can download it from the Kapling site.

Analog Karplus Strong Synthesis
This video captures a synth patch trying to model a plucked string.
The setup is MFB Osc-2 into LPG (both mode) into A-188-1 BBD into another LPG (Filter only, to get rid of the BBD clock bleeding through). Pitch of the Osc and Delay clock of the BBD is sequenced by the MAQ16/3. A bit of reverb is added.
This video, Karplus Funk, demonstrates Karplus-Strong synthesis with a modular synth.
Patch details:
- Doepfer A-188-1 512 BBD, A-131 VCA, and A-140 ADSR (foreground).
- Doepfer A-121 filter in low pass modulated by another A-140 (background).
- Percussion is Doepfer A-111 and A-117.
- Sequencing is A-152 and A-160/161.
Karplus-Strong string synthesis is a type of physical modelling synthesis that feeds a short waveform through a filtered delay line to model acoustic sounds, such as hammered or plucked strings or some types of percussion.
