Thinksynth is a modular synthesizer for Linux written in C++. It uses the JACK Audio Connection Kit for sound input and output, and ALSA for MIDI processing. Instruments are created with .dsp files, which define a network of Thinksynth modules using a simple interpreted language. A collection of example .dsp files is available in the source distribution.
