DISC Make Noise WoggleBug Random Voltage Generator (10HP)

Full Description

The user manual for the WoggleBug, containing technical data and instructions for use, can be accessed here.

Controls & I/Os

• Smooth VCO Out: Shark's Fin wave audio rate signal controlled by the Ego Input, Ego/Id pannel setting, Influence CV IN, and Clock Rate/Chaos controls; 10Vpp.
• Ring-Mod Out: Pulse Wave Audio rate signal, ring modulated product of Smooth VCO, Woggle VCO, and audio rate signal at the Influence IN (if present). It gets very messy, very quickly. The digital nature of the Ring-Mod circuit makes simple waveforms (Pulse, Square, Triangle, Sine, Saw) almost necessary to achieve something remotely musical. But don't let that stop you from pumping Motown samples into this circuit; 10Vpp.
• Woggle VCO Out: Square Wave audio rate signal, controlled by Woggle panel control, Ego IN, Ego/Id Balance Control, Influence CV IN, and Clock Rate/Chaos controls; 10Vpp.
• Ego/Id Balance Control: With nothing inserted into the Ego input, this sets the range of probably values. Turning this control counter-clockwise, the random values generated by the system tend to "cluster." With a signal applied to the Ego IN, it allows that external signal to be balanced with the internal signal source to generate random voltages.
• Ego Input (External Input for S&H): Signals applied here will be injected directly to the incertainly, beating heart of the WoggleBug. Accepts CV or audio rate signals; expects 10Vpp max.
• Stepped Out: At lower clock rates, the Stepped Random Voltage appears here: new value occurring at every clock pulse indicated by the blue System Clock LED. At higher (audio) clock rates, bit reduction effects may be achieved by inserting an audio signal into Ego IN and setting Ego/Id Balance fully counter-clockwise; 10Vpp range.
• Stepped Out LED: Visual indication of approximate Stepped Random Voltage value.
• Influence In: CV and/or audio signal input that performs the following duties: Modulates frequency of Smooth and Woggle VCOs, inputs to the Ring-Mod circuit, and level shifts the Woggle CV signal. Responds 0V to 10V.
• Smooth Out: Smooth Control Voltage appears here, the smoothness of which is set by the Clock Rate/Chaos control; 0V to 10V.
• Woggle Control: Sets how quickly (or slowly) the Woggle circuit is able to catch the Smooth/Stepped circuit. Clockwise slows the Woggle CV, counter-clockwise speeds it up.
• Speed CV Attenuator: Unipolar attenuator for Speed CV In. Normalled to 8V.
• Speed CV In: Unipolar control signal input for Speed parameter. Normalled to +8V so that with nothing patched, the associated Speed CV attenuator will extend the internal clock generator range up to around 200Hz; range 0V to +8V.
• External Clock In: Any signal may be applied here, allowing for independent control of rate and smoothness.
• System Clock LED: Displays rate of Sample and Hold clock. When a signal is applied to the External Clock In, shows the rate of the incoming clock/rising edge.
• Disturb Button: Direct control of the Sample and Hold circuit. Pressing samples, and holding holds.
• Speed Control: Dual purpose control that sets the rate of the Wogglebug Internal Clock generator and the lag processor feeding the Smooth CV circuit. Turning it counter-clockwise slows the system and smooths its response. Turning it clockwise quickens the system with the smooth CV response becoming jittery. Internal Clock generator range is 1 minute per cycle up to around 40Hz (extended range pushes upper limit to around 200Hz).
• Burst Out: Square random gate signal, synced to the Clock and influenced by the Steeped, Smooth, and Woggle controls; 0 to +10V.
• Burst Out LED: Visual representation of random gates.
• Clock Out: Square clock signal from the internal clock generator. Not influenced by signal at External Clock In; 0V to +10V.
• Internal Clock LED: Displays the rate of the internal clock. Not affected by External Clock In.
