![]() That said, they include independent CV ins and outs and can be patched to control other destinations. The 1045 Synthesizer includes two independent envelope generators: the one the left controls filter cutoff frequency the one at far right controls VCA amplitude. Osc Out jack- Raw oscillator waveform output, dependent on wave selector switch settings. Moving the knob left or right narrows its width as well as the thickness of sound until it almost disappears at its extremes. Its default setting of 50% outputs a perfect square wave, rich in odd-order harmonics. Pulse Width (PW)- This sets the width or "duty-cycle" of the pulse wave (the very bottom waveform on the panel). Because audio frequencies are inherently exponential in nature, the resulting frequency rises and falls exactly one octave. ![]() #Osculator wave icon modFor example, if the base frequency is 1000 Hz, and a bipolar wave is applied to the mod CV input, the frequency falls to 500 Hz and rises to 2000 Hz. It defaults to center zero position.Īll of 1045's mod inputs are exponential, that is for a given mod input voltage, the mod amount increases as frequency increases. The attenuator knob is bipolar it allow positive (turn right) or inverted voltage control (turn left). It's useful for adding vibrato with an LFO, siren noises, envelope-controlled pitch sweeps, etc. The Off position disables the oscillator - this is useful for using other sections to process signals from other modules.įreq Mod jack and attenuator- Used for externally modulating the oscillator frequency. The pulse wave's duty-signal (i.e., width) can be set using the Pulse Width knob. Oscillator Wave selector- Five waveforms are available: sine, triangle, square, ramp, and pulse waves. The Fine control allows continuous fine pitch control and is configured as a "multiplier" with center position being nominal and a range of 1/2 pitch to the left or double the pitch to the right (i.e., +/- one octave). Typically this would come from the Pitch jack in the IO Panel CV Out section, or from a sequencer CV out.įrequency / Coarse and Fine- The Coarse control sets the base frequency over a nine-octave range, in octave increments. Oscillator enabled lamp- Illuminates when the Oscillator Wave selector knob set to any position other than Off.ġV/Oct jack- Accepts a CV input for pitch. The 1045 Synthesizer includes a single oscillator. Though it sacrifices a few controls and inputs, it essentially contains the equivalent of a 1004 oscillator, a 1006 lowpass filter, two 1003 envelope generators, and a VCA. ![]() The 1045 Synthesizer Voice Module packs an entire 2500-style voice into one compact module. ![]()
