Two modes of gain response are available: This resonant peak will break into oscillation at clockwise settings of the regeneration pot, creating a voltage controlled sine wave generator. A sawtooth waveform is recommended for best synchronization results. Number indications on the Range switch correspond to traditional organ pipe range notations. Four waveforms are available:

Using all original documentation as well as circuit board and art files for every module, Moog Engineers have painstakingly recreated this powerful and portable analog system. Four waveforms are available: Go to synthesizers MOOG. S-Trigger is needed to operate from external sources.
Like the Oscillator, this is one of the building blocks of analog synthesis. Each individual module is hand-stuffed osciloator the components are hand-soldered to circuit boards using traditional wiring methods.

There are no reviews to display. The A Fixed Filter Bank is a non-voltage controlled modifier, which emphasizes or reduces the gain of the center frequency bands indicated on each of the eight center pots, in addition to the cutoff points set by low pass oscillahor high pass filters at either frequency extreme.
This resonant peak will oxcillator into oscillation at clockwise settings of the regeneration pot, creating a voltage controlled sine wave generator.

Two voltages are generated: They are wired in groups to a common A Oscillator Driver, which provides both exponential frequency control and rectangular width voltage control. Two ranges are provided on the Frequency potentiometer: Two modes of gain response are available: Register a new account.
A resultant lower frequency concentration for Pink Noise marks the difference between the two outputs, with white noise appearing in even intensity throughout the audio spectrum. The basic cutoff frequency of the Low Pass Filter is determined by the combination of fixed control voltage and frequency range in addition to the control input signals. A sawtooth waveform is recommended for best synchronization results.
The Envelope Generator requires an S-trigger to operate. Only total units will be made and sold worldwide.
Each Model 15 is hand-built to its original Moog factory specifications and is a true recreation of the original. This limited edition reissue of the Moog oscollator Model 15 is built to order, and is available in very limited quantities. Moving clockwise from zero gain to unity with input, these attenuators can be used for reducing the effect of a control upon a voltage controlled module, providing oscilltor to three variable outputs from a single source input or reducing the gain of an entire signal complex.
All waveform outputs can be used concurrently if oscillahor. Parallel outputs are provided for both noise sources. The Model 15 design focuses on speed, creativity and simplicity while still providing the enormous sonic depth and dimension found only in a vintage Moog modular synthesizer.
All manual controls on this module can be moved or switched during operation. The A Low Pass Filter attenuates frequencies above the fixed control voltage cutoff point at a rate of 24dB per octave. Oscillatro Model 15 oscillators offer rectangular wave forms in it’s specs as well.
External sources must be converted to the S-trigger format. Only Model 15s will be made. The overall range of the FCV pot is determined by the Frequency Range switch, which moves the frequency cutoff range in two-octave steps. Control inputs for frequency and rectangular width are summing.
