Scanned Synth VST is the first VST plug-in to implement “Scanned Synthesis” – until now, this new synthesis technology has only been available to users of Csound and Max. Scanned Synth VST is a revolutionary musical instrument as well as a tool for creating sounds that have never been heard before. Many have described using it as a totally refreshing experience, inspiring whole new pieces of music or avenues of experimentation. What’s more… It’s totally free!
Scanned Synth VST is only available for Microsoft Windows-based PCs.
Scanned Synthesis represents a powerful and efficient technique for animating wavetables and controlling them in real-time. Developed by Bill Verplank, Rob Shaw, and Max Mathews between 1998 and 1999 at Interval Research, Inc. it is based on the psychoacoustics of how we hear and appreciate timbres and on our motor control (haptic) abilities to manipulate timbres during live performance.
Scanned Synthesis involves a slow dynamic system whose frequencies of vibration are below about 15 Hz. The ear cannot hear the low frequencies of the dynamic system. So, to make audible frequencies, the “shape” of the dynamic system, along a closed path, is scanned periodically. The “shape” is converted to a sound wave whose pitch is determined by the speed of the scanning function. Pitch control is completely separate from the dynamic system control. Thus timbre and pitch are independent. This system can be looked upon as a dynamic wave table. The model can be compared to a slowly vibrating string, or a two dimensional surface obeying the wave equation.
