"A true modular synthesizer is a synthesizer where the different sound generators, processors and control facilities are presented as independent objects without preconceived signal and/or control paths inbetween. The musician/composer chooses the combination of modules and connects them according to the musical idea, essentially creating a new instrument for each "patch".

This was the way all synthesizers were designed in the beginning. Soon some manufacturers discovered that it was more commercially successful to pre-package the synthesizer in a certain way, locking it into a single patch with just a few choices available to the musician and attaching a piano keyboard to the circuit. The word "synthesizer" quickly became synonymous with this design, often even called "keyboard" and used almost exclusively by pianists. Most people out there are not even aware of the modular synthesizer design. In the process of commercializing the synthesizer its abstract sound world had to be mainstreamed by letting it imitate acoustic instruments - strings, brass etc. Synthesizer quality was measured in terms of how realistic its sounds were.

The synthesizer is so much more."

Update via the comments: the modules are from the Buchla 200 series.
