- Page 2 “pre-wired” internally. This means that Big Blue will produce and output sound without any patching. You can extend the functionality by using the patch bay. Big Blue provides for eight voice polyphony, allowing you to use up to eight voices from a single input. Signal Path...
- Page 3 Big Blue Manual August, • Voltage Controlled Oscillator (VCO) • Low Frequency Oscillator (LFO) • Voltage Controlled Filter (VCF) • Envelope Generator (EG) • Voltage Controlled Amplifier (VCA) The LFO has the ability to a ect parameters on the VCO and VCF using internal routing. The VCO and EG can both be overridden by external inputs, and the EG can be bypassed completely.

- Page 5 Big Blue is divided into discrete components each with specific functionality. VCO (Voltage Controlled Oscillator) Figure : Big Blue contains three Voltage Controlled Oscillators, with each one being able to be overridden by external audio. Coarse The Coarse parameter provides a coarse tuning of the oscillator. It provides adjustment from one octave below to one octave above the base frequency fed into the oscillator itself.
- Page 6 Big Blue Manual August, Shape The shape parameter changes between four oscillation modes. Sine Wave provides a smooth sounding tone, and is the fundamental building block of sound. A sine wave provides a single frequency with no harmonics. Triangle Wave provides two sloping sides with a sharp peak. Triangle waves provide a sharper sound with harmonics at the inverse square of its harmonic number.
- Page 7 Big Blue Manual August, LFO (Low Frequency Oscillator) Figure : There are three Low Frequency Oscillators that can a ect di erent aspects of the sound, ranging from altering portions of the VCO or altering portions of the VCF. These LFOs are bipolar, meaning that they cycle between -1v and 1v.
- Page 8 Big Blue Manual August, Route Routing in Big Blue is modified in the Route module. Each LFO can be routed to any of the following parameters. They are considered additive. Parameter Description Not Routed Pulse Width on Oscillator -FREQ Frequency on Oscillator...
- Page 9 Big Blue Manual August, EG (Envelope Generator) Figure : Eastside incorporates an ADSR Envelope Generator, featuring an Attack, Decay, Sustain, and Release. This envelope alters the characteristics of the sound by allowing for a timed note release, based on the parameters and the length of the Gate input.
- Page 10 VCF (Voltage Controlled Filter) Figure : Big Blue provides two Voltage Controlled Filters, a Ladder Filter, similar to what you would find on a Moog synthesizer, and a State Variable Filter. Each of these has multiple modes to modify the sound using subtractive synthesis.
- Page 11 Input Figure : Big Blue o ers a range of CV inputs to adjust parameters or to override built in modules. Each VCO has CV inputs for Coarse, Fine, Pulse Width, and Mix. Each VCO can be overridden by an audio input, bypassing the oscillator and inserting right before the Mixer.
- Page 12 Big Blue Manual August, Outputs Output Figure : Big Blue o ers broken out outputs from each VCO and LFO. Each waveform is output separately, regardless of the shape of each oscillator. SV Modular...
