"The Serge Modular Systems NEW TIMBRAL OSCILLATOR (NTO) is the state-of--the-art VCO, featuring exceptional range, superb temperature stability, and accurate tracking. Dynamic depth frequency modulation and voltage control of waveform allow unprecedented control over a wide range of sound qualities.EXPONENTIAL 1 VOLT/OCTAVE RESPONSE
Exponential response parallels the response of human hearing perception as well as musical pitch structure. With multiple oscillators, each must respond exponentially to control voltages to allow transposition from key to key and to produce alternative equal-tempered tunings such as quarter and third tones. In addition, the one-volt-per-octave response assures that the New Timbral Oscillator is compatible with most keyboard and computer controllers.
ACCURATE TRACKING
When two or more oscillators are tuned, it is expected that they will remain in tune throughout their entire range (in other words, that they track). Even two oscillators which track within a fraction of a semitone will be out of tune at the extremities of their range. Therefore, the New Timbral Oscillators have been designed so that any two will track within one cycle/second throughout their entire musical range.
TEMPERATURE STABILITY
Instability of pitch with changes in temperature is the criticism of most synthesizer VCO's. Performers are aware of the disastrous effects of temperature when they must desperately re-tune oscillators that have drifted during a live performance. The temperature sensitive components are kept at an even 120 degrees by a solid-state "oven". Thus temperature stability is guaranteed from 50 degrees to 100 degrees F.
