Notes: The Looping ADSR is an extremely versatile envelope generator. It can act as a traditional ADSR envelope requiring a gate signal to activate or as a looping ADSR. Envelopes can be output with both linear and exponential curves. In Loop Mode it repeats the cycle of Attack, Decay, & Release. Once the Release phase is complete, it loops back to the Attack and begins the cycle again. The Looped envelope can be further manipulated with the Loop Scale knob. Loop Scale shrinks the overall size of the envelope while keeping the ratio of A:D:R identical. All knobs on the Looping ADSR have CV input. As with all Hungry Robot "Modular Boxes" the Looping ADSR can be powered with a simple 9V DC, Negative Center power supply.

KNOBS
-ATTACK: Sets the attack length (1st stage of ADSR cycle). Determines how long it takes to come to full voltage after gate is applied (up to 10 sec.)
-DECAY: Sets the decay length (2nd stage of ADSR cycle). Determines how long it takes to go from full voltage to sustain voltage (up to 10 sec.)
-SUSTAIN: Sets the sustain level. Determines what voltage the envelope returns to after decay stage
-RELEASE: Sets the release length (Final stage of ADSR cycle). Determine how long it takes to return to 0V after gate is released (up to 10 sec.)
-LOOP SCALE: When in loop mode, this knob scales down the length of the envelope while keeping the ratios identical

SWITCHES
-LIN/EXP: Selects the envelope type: linear vs. exponential curve
-LOOP/ADSR: Switches between Loop and ADSR mode. LOOP turns the loop on. ADSR is a traditional ADSR requiring a gate signal
-RPT./GATE: Works only in LOOP mode. RPT. automatically repeats the loop without a gate. GATE mode requires a gate to begin looping.

PATCH POINTS
-LS.CV: CV input for Loop Scale. Allows for CV control of this parameter.
-A.CV: CV input for Attack. Allows for CV control of this parameter.
-D.CV: CV input for Decay. Allows for CV control of this parameter.
-S.CV: CV input for Sustain. Allows for CV control of this parameter.
-R.CV: CV input for Release. Allows for CV control of this parameter.
-GATE: Gate input for ADSR mode as well as Gate/Loop mode
-OUT: Output of final envelope for all modes.

Notes: The 4 Channel Mixer is a basic DC coupled mixer with 4 inputs and 4 attenuators. DC coupled means that it will accept both DC and AC (Audio) signals. As with all Hungry Robot "Modular Boxes" the 4 Channel Mixer can be powered with a simple 9V DC, Negative Center power supply.

PATCH POINTS
-IN (x4): Patch in any audio or CV signal to any of the 4 inputs. (NOTE: Avoid mixing CV and Audio)
-OUT: This output is the sum of the four channels

KNOBS
-LEVEL (x4): Each input has its own attenuator that allow you to bring down the level of the inputs

Notes: The Hungry Robot Sample & Hold provides basic S&H functionality with some added bells and whistles. It uses an internal clock dialed into a very useful range. If the internal clock rate is not to your liking, you can bypass the Rate knob by patching a clock signal into Clk In. The Sample & Hold has a built in attenuverter giving a bit of added control over the random voltages that are outputted. White noise out for uses elsewhere. Traditionally a S&H samples voltages from chaotic white noise, but E.In allows you to bypass the white noise and patch in your own sample source (i.e. patching an LFO in for a bit crushed LFO). As with all Hungry Robot "Modular Boxes" the Sample & Hold can be powered with a simple 9V DC, Negative Center power supply.

KNOBS
-MINUS/PLUS: Attenuverter for output. Allows you to sweep between positive and negative voltage outputs.
-RATE: On board clock source ranging from approximately 25ms to 1000ms.

PATCH POINTS
-E.IN: Bypasses internal white noise as a sample source. Patch in any CV source that you want to sample from
-STATIC: Taps into white noise output (0-5V range)
-CLK IN: Bypasses internal clock with your provided external clock
-S&H OUT: Two buffered outputs of S&H voltage

Notes: Lovely little mono filter module in a compact desktop format. Based on the classic Prophet 5 filter, ideal for processing synths and signals, hooking up to Eurorack or other Hungry Robot modules.

Supplier's Notes:

The Hungry Robot VCF is an all analog, 4-pole low pass filter with a self-oscillating resonance control. It is a close replication of the filter circuit found on the famous Prophet 5. It uses a HM2040 which is a high quality, faithful replication of the original SSM2040 chip. This resonant filter has a beautiful tonal quality. The over-sized knobs provide a satisfying tactile response. The cutoff frequency can be controlled by external control voltage. It has a built-in attenuator and invert switch for the incoming CV. CV input does not track at 1V/Oct, but is scaled to act as a VCA when a 5V signal is applied to CV input. As with all Hungry Robot "Modular Boxes" the VCF can be powered by a simple 9V DC, Negative Center power supply.

KNOBS
-FREQUENCY: Sweeps the cutoff frequency of the filter.
-CV: Attenuator for incoming CV input.
-RESONANCE: Sets resonance of filter. Small volume drop is to be expected. Will self-oscillate at higher settings.

SWITCHES
-INVERT: Inverts the incoming CV input. Toggle to the right to invert incoming CV

PATCH POINTS
-IN: Patch Audio Signal In
-CV: CV input for Frequency. Allows for CV control of this parameter.
-OUT: Patch Audio Signal Out
