Laurie Spiegel plays Alles Synth

“This 1977 tape is one of the earliest examples of purely digital realtime audio synthesis. It manages to achieve an analog synth sounding quality, but is entirely digital synthesis and signal processing. The interactive software I wrote and am playing in this video recycles my keyboard input into an accompaniment to my continued playing, which is why I called it a ‘concerto generator’. I use part of one of the keyboards for control data entry, and the small switches upper right to access pre-entered numerical patterns. The sliders are mainly pre-Yamaha FM synthesis parameter controls, for the number and amplitude and frequency of the FM pair modulators and carriers…” Laurie Speigel
