Buchla 400 synthesizer

The Buchla 400 belongs to the era of synthesizers that incorporate microprocessor-based integrated circuits. In addition to being more reliable and less expensive to manufacture, the synthesizers of the microprocessor era were, to varying extents, also programmable, meaning that various parameters could be stored either within the instrument’s internal memory or onto an external device. Although it was never a commercial success, the Buchla 400 stands as among the most sophisticated digital-analog hybrid synthesizers of the time. The various input and output jacks located on the instrument’s front panel may also be connected to modules from the 100 and 200 Series so as to expand its capabilities.
