In 1983 Yamaha beginning with the release of DX-7 first truly digital programmable algorithm synthesizer based on the FM synthesis technology. DX-7 became great commercial success with over 180,000 sold units. The DX7 use a type of synthesis called "Frequency Modulation" developed by Professor John Chowning at Stanford University in the 1970s. Yamaha DX synthesizers use "operators" to generate sound Instead of VCOs, VCAs and VCFs known from the subtractive analogue synthesizers. An operator is basically a digital sine wave generator combined with an complex envelope generator that can be used alone or in combination with other operators. A combination of operators is called an "algorithm". The operators can be connected "horizontally" so that each contributes its own pitch to the sound (additive synthesis), or "vertically". In vertically connected configurations, the upper operator modulates the lower operator at a precisely controllable frequency ratio, resulting in highly complex waveforms that are the key to the DX system´s incredible sound. Some operators even permit the application of feedback so, effectively, they can be made to modulate themselves. Further, the sophisticated envelope generators incorporated in each operator make it possible to produce time-based timbre variations as well as level variations. The DX7 was one of the first synths with a full complement of MIDI ports. It also has a unique breath controller input port. This device allowed the user to manipulated the instruments timbre using breath pressure via a mouth held tube. DX/TX series were available either as a 6-operator or 4-operator synths.
