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.
