  • Page 2 The East Beast is a a direct path to that sound. I love the East Beast for how immediate it is and how it welcomes both new and veteran artists to modular analog synthesis with a sense of humor and without pretense. Please use this synthesizer as a launch pad for experimentation and fun in the search for your sound because that’s exactly what we at Pittsburgh, and our friends at Cre8audio designed it for.

  • Page 5 Connect different functions using patch cables to create complex sounds and textures. The East Beast signal path is divided into two types of signals: audio signals and control voltages. The audio signal is the sound that is produced. The audio signal path starts at an oscillator or other sound source.
  • Page 6 3 East Beast Overview 3.4 Internal Patching: The East Beast utilizes internal patching to create a single oscillator synth voice that does not require patch cables to play. To modify the internal patch or to create something completely new, all of the internal routing can be bypassed using patch cables. This allows total patching freedom without the constrains of a fixed voice architecture.
  • Page 7: Individual Modules

    The East Beast can be organized into 6 independent Modules. Oscillator, filter, envelope, VCA, LFO, and button keyboard. Each module controls one or more functions and can operate on its own or can be patched into any other module within the East Beast or other Eurorack format modules.

  • Page 11 The VCA is a high quality linear voltage controlled amplifier. Used to attenuate an audio or cv signal using voltage control. In the East Beast, the VCA is the last stage of the synth voice signal chain and controlled with the output of the Envelope to musically shape the volume of the synthesizer voice.
